FN6115.1  
±15kV ESD Protected, 3.3V, Full Fail-s afe,  
Low Power, High Speed or Slew Rate  
Limited, RS-485/RS-422 Trans ceivers  
Features  
• Pb-Free Plus Anneal (RoHS Compliant)  
• RS-485 I/O Pin ESD Protection . . . . . . . . . . ±15kV HBM  
The Intersil ISL8307XE are BiCMOS 3.3V powered, single  
transceivers that meet both the RS-485 and RS-422  
standards for balanced communication. These devices have  
very low bus currents (+125µA/-100µA), so they present a  
true “1/8 unit load” to the RS-485 bus. This allows up to 256  
transceivers on the network without violating the RS-485  
specification’s 32 unit load maximum, and without using  
repeaters. For example, in a remote utility meter reading  
system, individual meter readings are routed to a concentrator  
via an RS-485 network, so the high allowed node count  
minimizes the number of repeaters required.  
- Class 3 ESD Level on all Other Pins . . . . . . >7kV HBM  
• Full Fail-safe (Open, Short, Terminated/Floating)  
Receivers  
• Hot Plug - Tx and Rx Outputs Remain Three-state During  
Power-up  
• True 1/8 Unit Load Allows up to 256 Devices on the Bus  
• Single 3.3V Supply  
• High Data Rates. . . . . . . . . . . . . . . . . . . . . up to 20Mbps  
• Low Quiescent Supply Current . . . . . . . . . . 800µA (Max)  
- Ultra Low Shutdown Supply Current . . . . . . . . . . 10nA  
Receiver (Rx) inputs feature a “Full Fail-Safe” design, which  
ensures a logic high Rx output if Rx inputs are floating,  
shorted, or terminated but undriven.  
• -7V to +12V Common Mode Input/Output Voltage Range  
• Half and Full Duplex Pinouts  
Hot Plug circuitry ensures that the Tx and Rx outputs remain  
in a high impedance state while the power supply stabilizes.  
• Three State Rx and Tx Outputs Available  
The ISL83070E through ISL83075E utilize slew rate limited  
drivers which reduce EMI, and minimize reflections from  
improperly terminated transmission lines, or unterminated  
stubs in multidrop and multipoint applications. Slew rate limited  
versions also include receiver input filtering to enhance noise  
immunity in the presence of slow input signals.  
• Current Limiting and Thermal Shutdown for driver  
Overload Protection  
• Tiny MSOP package offering saves 50% board space  
Applications  
• Automated Utility Meter Reading Systems  
The ISL83070E, ISL83071E, ISL83073E, ISL83076E,  
ISL83077E are configured for full duplex (separate Rx input  
and Tx output pins) applications. The half duplex versions  
multiplex the Rx inputs and Tx outputs to allow transceivers  
with output disable functions in 8 lead packages.  
• High Node Count Systems  
• Field Bus Networks  
• Security Camera Networks  
• Building Environmental Control/ Lighting Systems  
• Industrial/Process Control Networks

FUNCTION  
Receiver output: If A-B ≥ -50mV, RO is high; If A-B ≤ -200mV, RO is low; RO = High if A and B are unconnected (floating) or shorted.  
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high.  
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high, and are high impedance when DE is low.  
Driver input. A low on DI forces output Y low and output Z high. Similarly, a high on DI forces output Y high and output Z low.

4. All currents into device pins are positive; all currents out of device pins are negative. All voltages are referenced to device ground unless otherwise  
specified.  
5. Supply current specification is valid for loaded drivers when DE = 0V.  
6. Applies to peak current. See “Typical Performance Curves” for more information.  
7. When testing devices with the shutdown feature, keep RE = 0 to prevent the device from entering SHDN.  
8. When testing devices with the shutdown feature, the RE signal high time must be short enough (typically <100ns) to prevent the device from  
entering SHDN.  
9. Versions with a shutdown feature are put into shutdown by bringing RE high and DE low. If the inputs are in this state for less than 50ns, the parts  
are guaranteed not to enter shutdown. If the inputs are in this state for at least 600ns, the parts are guaranteed to have entered shutdown. See  
“Low-Power Shutdown Mode” section.  
10. Keep RE = VCC, and set the DE signal low time >600ns to ensure that the device enters SHDN.  
11. Set the RE signal high time >600ns to ensure that the device enters SHDN.

long as 4000’, so the wide CMR is necessary to handle  
ground potential differences, as well as voltages induced in  
the cable by external fields.  
Application Information  
RS-485 and RS-422 are differential (balanced) data  
transmission standards for use in long haul or noisy  
environments. RS-422 is a subset of RS-485, so RS-485  
transceivers are also RS-422 compliant. RS-422 is a point-  
to-multipoint (multidrop) standard, which allows only one  
driver and up to 10 (assuming one unit load devices)  
receivers on each bus. RS-485 is a true multipoint standard,  
which allows up to 32 one unit load devices (any  
combination of drivers and receivers) on each bus. To allow  
for multipoint operation, the RS-485 spec requires that  
drivers must handle bus contention without sustaining any  
damage.  
Receiver Features  
These devices utilize a differential input receiver for maximum  
noise immunity and common mode rejection. Input sensitivity  
is better than ±200mV, as required by the RS-422 and RS-485  
specifications.  
Receiver input resistance of 96kΩ surpasses the RS-422  
spec of 4kΩ, and is eight times the RS-485 “Unit Load (UL)”  
requirement of 12kΩ minimum. Thus, these products are  
known as “one-eighth UL” transceivers, and there can be up  
to 256 of these devices on a network while still complying  
with the RS-485 loading spec.  
Another important advantage of RS-485 is the extended  
common mode range (CMR), which specifies that the driver  
outputs and receiver inputs withstand signals that range from  
+12V to -7V. RS-422 and RS-485 are intended for runs as  
Receiver inputs function with common mode voltages as  
great as +9V/-7V outside the power supplies (i.e., +12V and

-7V), making them ideal for long networks where induced  
voltages, and ground potential differences, are realistic  
concerns.  
for board level protection structures (e.g., transient  
suppression diodes), and the associated, undesirable  
capacitive load they present.  
All the receivers include a “full fail-safe” function that  
guarantees a high level receiver output if the receiver inputs  
are unconnected (floating) or shorted. Fail-safe with shorted  
inputs is achieved by setting the Rx upper switching point to  
-50mV, thereby ensuring that the Rx sees 0V differential as a  
high input level.  
Receivers easily meet the data rates supported by the  
corresponding driver, and all receiver outputs - except on the  
ISL83071E and ISL83077E- are tri-statable via the active  
low RE input.  
Data Rate, Cables, and Terminations  
RS-485/422 are intended for network lengths up to 4000’,  
but the maximum system data rate decreases as the  
transmission length increases. Devices operating at 20Mbps  
are limited to lengths less than 100’, while the 250kbps  
versions can operate at full data rates with lengths of several  
thousand feet.  
Twisted pair is the cable of choice for RS-485/422 networks.  
Twisted pair cables tend to pick up noise and other  
electromagnetically induced voltages as common mode  
signals, which are effectively rejected by the differential  
receivers in these ICs.  
Proper termination is imperative, when using the 20Mbps  
devices, to minimize reflections. Short networks using the  
250kbps versions need not be terminated, but, terminations  
are recommended unless power dissipation is an overriding  
concern.  
In point-to-point, or point-to-multipoint (single driver on bus)  
networks, the main cable should be terminated in its  
characteristic impedance (typically 120Ω) at the end farthest  
from the driver. In multi-receiver applications, stubs  
connecting receivers to the main cable should be kept as  
short as possible. Multipoint (multi-driver) systems require  
that the main cable be terminated in its characteristic  
impedance at both ends. Stubs connecting a transceiver to  
the main cable should be kept as short as possible.  
Driver Features  
The RS-485/422 driver is a differential output device that  
delivers at least 1.5V across a 54Ω load (RS-485), and at  
least 2V across a 100Ω load (RS-422). The drivers feature  
low propagation delay skew to maximize bit width, and to  
minimize EMI.  
All drivers are tri-statable via the active high DE input, except  
on the ISL83071E and ISL83077E.  
The 250kbps and 500kbps driver outputs are slew rate  
limited to minimize EMI, and to reduce reflections in  
unterminated or improperly terminated networks. Outputs of  
the ISL83076E, ISL83078E drivers are not limited, so faster  
output transition times allow data rates of at least 20Mbps.  
Hot Plug Function  
When a piece of equipment powers up, there is a period of  
time where the processor or ASIC driving the RS-485 control  
lines (DE, RE) is unable to ensure that the RS-485 Tx and  
Rx outputs are kept disabled. If the equipment is connected  
to the bus, a driver activating prematurely during power up  
may crash the bus. To avoid this scenario, the ISL8307XE  
family incorporates a “Hot Plug” function. During power up,  
Built-In Driver Overload Protection  
As stated previously, the RS-485 spec requires that drivers  
survive worst case bus contentions undamaged. These  
devices meet this requirement via driver output short circuit  
current limits, and on-chip thermal shutdown circuitry.  
The driver output stages incorporate short circuit current  
limiting circuitry which ensures that the output current never  
exceeds the RS-485 spec, even at the common mode  
voltage range extremes. Additionally, these devices utilize a  
foldback circuit which reduces the short circuit current, and  
thus the power dissipation, whenever the contending voltage  
exceeds either supply.  
circuitry monitoring V ensures that the Tx and Rx outputs  
CC  
remain disabled for a period of time, regardless of the state of  
DE and RE. This gives the processor/ASIC a chance to  
stabilize and drive the RS-485 control lines to the proper states.  
ESD Protection  
All pins on these devices include class 3 (>7kV) Human  
Body Model (HBM) ESD protection structures, but the  
RS-485 pins (driver outputs and receiver inputs)  
incorporate advanced structures allowing them to survive  
ESD events in excess of ±15kV HBM. The RS-485 pins are  
particularly vulnerable to ESD damage because they  
typically connect to an exposed port on the exterior of the  
finished product. Simply touching the port pins, or  
connecting a cable, can cause an ESD event that might  
destroy unprotected ICs. These new ESD structures  
protect the device whether or not it is powered up, protect  
without allowing any latchup mechanism to activate, and  
without degrading the RS-485 common mode range of -7V  
to +12V. This built-in ESD protection eliminates the need  
In the event of a major short circuit condition, devices also  
include a thermal shutdown feature that disables the drivers  
whenever the die temperature becomes excessive. This  
eliminates the power dissipation, allowing the die to cool. The  
drivers automatically re-enable after the die temperature  
drops about 15 degrees. If the contention persists, the thermal  
shutdown/re-enable cycle repeats until the fault is cleared.  
Receivers stay operational during thermal shutdown.  
Low Power Shutdown Mode  
These CMOS transceivers all use a fraction of the power  
required by their bipolar counterparts, but some also include  
a shutdown feature that reduces the already low quiescent  
I
to a 10nA trickle. These devices enter shutdown  
CC  
whenever the receiver and driver are simultaneously  
disabled (RE = V  
CC  
and DE = GND) for a period of at least

600ns. Disabling both the driver and the receiver for less  
than 50ns guarantees that the transceiver will not enter  
shutdown.  
Note that receiver and driver enable times increase when the  
transceiver enables from shutdown. Refer to Notes 7-11, at the  
end of the Electrical Specification table, for more information.
