DATASHEET
±60V Fault Protected, 5V, RS-485/RS-422 Transceivers
with ±25V Common Mode Range
ISL31490E, ISL31491E, ISL31492E, ISL31493E, ISL31495E,
ISL31496E, ISL31498E
The ISL31490E, ISL31491E, ISL31492E, ISL31493E,
ISL31495E, ISL31496E, ISL31498E are fault protected, 5V
Features
• Fault protected RS-485 bus pins . . . . . . . . . . . . . . up to ±60V
powered, differential transceivers that exceed the RS-485 and
RS-422 standards for balanced communication. The RS-485
transceiver pins (driver outputs and receiver inputs) are
protected against faults up to ±60V. Additionally, the extended
common mode range allows these transceivers to operate in
environments with common mode voltages up to ±25V (>2x the
RS-485 requirement), making this RS-485 family one of the
most robust on the market.
• Extended common mode range. . . . . . . . . . . . . . . . . . . . ±25V
More than twice the range required for RS-485
• 1/4 unit load for up to 128 devices on the bus
• High transient overvoltage tolerance. . . . . . . . . . . . . . . . ±80V
• Full fail-safe (open, short, terminated) RS-485 receivers
• High Rx I for opto-couplers in isolated designs
OL
Transmitters deliver an exceptional 2.5V (typical) differential
output voltage into the RS-485 specified 54Ω load. This yields
better noise immunity than standard RS-485 ICs, or allows up
to six 120Ω terminations in star network topologies.
• Hot plug circuitry - Tx and Rx outputs remain three-state
during power-up/power-down
• Choice of RS-485 data rates. . . . . . . . . . 250kbps to 15Mbps
• Low quiescent supply current. . . . . . . . . . . . . . . . . . . . 2.3mA
• Ultra low shutdown supply current. . . . . . . . . . . . . . . . . . 10µA
• Pb-free (RoHS compliant)
Receiver (Rx) inputs feature a “Full Fail-safe” design, which
ensures a logic high Rx output if Rx inputs are floating, shorted,
or on a terminated but undriven (idle) bus. Rx outputs have high
drive levels - typically 15mA at V = 1V (for opto-coupled,
OL
isolated applications).
Applications
Half duplex (Rx inputs and Tx outputs multiplexed together)
and full duplex pinouts are available. See Table 1 on page 3 for
key features and configurations by device number.
• Utility meters/automated meter reading systems
• High node count systems
• PROFIBUS™ and field bus networks, and factory automation
• Security camera networks
For fault protected or wide common mode range devices with
cable invert (polarity reversal) please see the ISL32485E
datasheet.
• Building lighting and environmental control systems
• Industrial/process control networks

Driver (Tx) Features
Application Information
The RS-485/RS-422 driver is a differential output device that
RS-485 and RS-422 are differential (balanced) data
delivers at least 1.5V across a 54Ω load (RS-485), and at least
transmission standards used for long haul or noisy environments.
2.4V across a 100Ω load (RS-422). The drivers feature low
RS-422 is a subset of RS-485, so RS-485 transceivers are also
propagation delay skew to maximize bit width, and to minimize
RS-422 compliant. RS-422 is a point-to-multipoint (multidrop)
EMI, and all drivers are three-statable via the active high DE
standard, which allows only one driver and up to 10 (assuming
input.
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 specification requires that
drivers must handle bus contention without sustaining any
damage.
The 250kbps and 1Mbps driver outputs are slew rate limited to
minimize EMI, and to minimize reflections in unterminated or
improperly terminated networks. Outputs of the ISL31496E and
ISL31498E drivers are not limited, thus faster output transition
times allow data rates of at least 15Mbps.
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 long as
4000’, thus the wide CMR is necessary to handle ground
potential differences, as well as voltages induced in the cable by
external fields.
High Overvoltage (Fault) Protection
Increases Ruggedness
Note: The available smaller pitch packages (e.g., MSOP and
TDFN) may not meet the creepage and clearance (C&C)
requirements for ±60V levels. The user is advised to determine
his C&C requirements before selecting a package type.
The ISL3149xE is a family of ruggedized RS-485 transceivers
that improves on the RS-485 basic requirements, and therefore
increases system reliability. The CMR increases to ±25V, while
the RS-485 bus pins (receiver inputs and driver outputs) include
fault protection against voltages and transients up to ±60V.
Additionally, larger than required differential output voltages
The ±60V (referenced to the IC GND) fault protection on the
RS-485 pins, makes these transceivers some of the most rugged
on the market. This level of protection makes the ISL3149xE
perfect for applications where power (e.g., 24V and 48V supplies)
must be routed in the conduit with the data lines, or for outdoor
applications where large transients are likely to occur. When
power is routed with the data lines, even a momentary short
between the supply and data lines will destroy an unprotected
device. The ±60V fault levels of this family are at least five times
higher than the levels specified for standard RS-485 ICs. The
ISL3149xE protection is active whether the Tx is enabled or
disabled, and even if the IC is powered down.
(V ) increase noise immunity.
OD
Receiver (Rx) 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.
If transients or voltages (including overshoots and ringing)
greater than ±60V are possible, then additional external
protection is required.
Receiver input (load) current surpasses the RS-422 specification
of 3mA, and is four times lower than the RS-485 “Unit Load (UL)”
requirement of 1mA maximum. Thus, these products are known
as “one-quarter UL” transceivers, and there can be up to 128 of
these devices on a network while still complying with the RS-485
loading specification.
Widest Common Mode Voltage (CMV)
Tolerance Improves Operating Range
RS-485 networks operating in industrial complexes, or over long
distances, are susceptible to large CMV variations. Either of these
operating environments may suffer from large node-to-node
ground potential differences, or CMV pickup from external
electromagnetic sources, and devices with only the minimum
required +12V to -7V CMR may malfunction. The ISL3149xE’s
extended ±25V CMR is the widest available, allowing operation in
environments that would overwhelm lesser transceivers.
Additionally, the Rx will not phase invert (erroneously change
state) even with CMVs of ±40V, or differential voltages as large
as 40V.
The Rx functions with common mode voltages as great as ±25V,
making them ideal for industrial, or long networks where induced
voltages are a realistic concern.
All the receivers include a “full fail-safe” function that guarantees a
high level receiver output if the receiver inputs are unconnected
(floating), shorted together, or connected to a terminated bus with
all the transmitters disabled (i.e., an idle bus).
Rx outputs feature high drive levels (typically 22mA at V = 1V) to
OL
ease the design of optically coupled isolated interfaces.
Receivers easily meet the data rates supported by the
corresponding driver, and all receiver outputs are three-statable
via the active low RE input (except on the ISL31491E).
High V Improves Noise Immunity and
OD
Flexibility
The ISL3149xE driver design delivers larger differential output
The Rx in the 250kbps and 1Mbps versions include noise filtering
circuitry to reject high frequency signals. The 1Mbps version
typically rejects pulses narrower than 50ns (equivalent to
20Mbps), while the 250kbps Rx rejects pulses below 150ns
(6.7Mbps).

In point-to-point, or point-to-multipoint (single driver on bus like
RS-422) networks, the main cable should be terminated in its
characteristic impedance (typically 120Ω) at the end farthest
from the driver. In multireceiver applications, stubs connecting
receivers to the main cable should be kept as short as possible.
Multipoint (multidriver) 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.
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 ISL3149xE devices incorporate a “Hot
Plug” function. Circuitry monitoring V ensures that, during
power-up and power-down, the Tx and Rx outputs remain disabled,
CC
regardless of the state of DE and RE, if V is less than ≈3.5V. This

CC
gives the processor/ASIC a chance to stabilize and drive the RS-485
control lines to the proper states. Figure 12 illustrates the power-up
and power-down performance of the ISL3149xE compared to an
RS-485 IC without the Hot Plug feature.
As stated previously, the RS-485 specification requires that
drivers survive worst case bus contentions undamaged. These
transceivers meet this requirement via driver output short circuit
current limits, and on-chip thermal shutdown circuitry.
DE, DI = V
RE = GND
CC
The driver output stages incorporate a double foldback short
circuit current limiting scheme which ensures that the output
current never exceeds the RS-485 specification, even at the
common mode and fault condition voltage range extremes. The
first foldback current level (≈70mA) is set to ensure that the
driver never folds back when driving loads with common mode
voltages up to ±25V. The very low second foldback current
setting (≈9mA) minimizes power dissipation if the Tx is enabled
when a fault occurs.

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°C. If the
contention persists, the thermal shutdown/re-enable cycle repeats
until the fault is cleared. Receivers stay operational during thermal
shutdown.

RS-485/RS-422 are intended for network lengths up to 4000’,
but the maximum system data rate decreases as the
These CMOS transceivers all use a fraction of the power required
by competitive devices, but they also include a shutdown feature
transmission length increases. Devices operating at 15Mbps
may be used at lengths up to 150’ (46m), but the distance can be
increased to 328’ (100m) by operating at 10Mbps. The 1Mbps
versions can operate at full data rates with lengths up to 800’
(244m). Jitter is the limiting parameter at these faster data rates,
so employing encoded data streams (e.g., Manchester coded or
Return-to-Zero) may allow increased transmission distances. The
slow versions can operate at 115kbps, or less, at the full 4000’
(1220m) distance, or at 250kbps for lengths up to 3000’
(915m). DC cable attenuation is the limiting parameter, so using
that reduces the already low quiescent I to a 10µA trickle.
These devices enter shutdown whenever the receiver and driver

receiver for less than 60ns guarantees that the transceiver will
