DESCRIPTION
The SP483E is a half-duplex transceiver that meets the specifications of RS-485 and RS-422
serial protocols with enhanced ESD performance. The ESD tolerance has been improved on
this device to over ±15kV for both Human Body Model and IEC1000-4-2 Air Discharge
Method. This device is pin-to-pin compatible with Sipex's SP483 device as well as popular
industry standards. As with the original version, the SP483E features Sipex's BiCMOS
design allowing low power operation without sacrificing performance. The SP483E meet the
requirements of the RS-485 and RS-422 protocols up to 250kbps under load. The SP483E
is internally slew rate limited to reduce EMI and can meet the requirements of RS-485 and
RS-422 up to 250kbps. The SP483E is also equipped with a low power Shutdown mode.

DESCRIPTION...
Receivers...
The SP483E is a half-duplex differential
transceiver that meets the requirements of
RS-485 and RS-422. Fabricated with a Sipex
proprietary BiCMOS process, the SP483E
requires a fraction of the power of older bipolar
designs.
The SP483E receivers have differential inputs
with an input sensitivity as low as ±200mV.
Input impedance of the receivers is typically
15kΩ (12kΩ minimum). A wide common mode
range of -7V to +12V allows for large ground
potential differences between systems. The
receivers have a tri-state enable control pin.
A logic LOW on RE (pin 2) will enable the
receiver, alogicHIGHonRE(pin2)willdisable
the receiver.
The RS-485 standard is ideal for multi-drop
applications and for long-distance interfaces.
RS-485 allows up to 32 drivers and 32 receivers
to be connected to a data bus, making it an ideal
choice for multi-drop applications. Since the
cabling can be as long as 4,000 feet, RS-485
transceivers are equipped with a wide (-7V to
+12V) common mode range to accommodate
groundpotentialdifferences. BecauseRS-485is
a differential interface, data is virtually immune
to noise in the transmission line.
The SP483E receiver is rated for data rates up
to 250 Kbps. The receivers are equipped with
the fail-safe feature. Fail-safe guarantees that
the receiver output will be in a HIGH state when
the input is left unconnected.
Shutdown Mode...
Drivers...
TheSP483EisequippedwithaShutdownmode.
To enable the Shutdown state, both the driver
andreceivermustbedisabledsimultaneously. A
logic LOW on DE (pin 3) and a logic HIGH on
RE (pin 2) will put the SP483E into Shutdown
mode. In Shutdown, supply current will drop to
typically 1µA.
The driver outputs of the SP483E are differential
outputs meeting the RS-485 and RS-422 stan-
dards. The typical voltage output swing with no
load will be 0 Volts to +5 Volts. With worst case
loading of 54Ω across the differential outputs,
the drivers can maintain greater than 1.5V volt-
age levels. The drivers have an enable control
line which is active HIGH. A logic HIGH on DE
(pin3)willenablethedifferentialdriveroutputs.
A logic LOW on DE (pin 3) will tri-state the
driver outputs.
ESD TOLERANCE...
The SP483E device incorporates ruggedized
ESD cells on all driver output and receiver input
pins. The ESD structure is improved over our
previous family for more rugged applications
and environments sensitive to electro-static
discharges and associated transients. The
improved ESD tolerance is at least ±15kV
without damage nor latch-up.
The SP483E has internally slew rate limited
driver outputs to minimize EMI. The maximum
data rate for the SP483E drivers is 250 Kbps
under load.
There are different methods of ESD testing
applied:
a) MIL-STD-883, Method 3015.7
b) IEC1000-4-2 Air-Discharge
c) IEC1000-4-2 Direct Contact

systems. For system manufacturers, they must
guarantee a certain amount of ESD protection
since the system itself is exposed to the outside
environment and human presence. The premise
with IEC1000-4-2 is that the system is required
to withstand an amount of static electricity when
ESD is applied to points and surfaces of the
equipmentthatareaccessibletopersonnelduring
normal usage. The transceiver IC receives most
of the ESD current when the ESD source is
applied to the connector pins. The test circuit for
IEC1000-4-2 is shown on Figure 10. There are
two methods within IEC1000-4-2, the Air
Discharge method and the Contact Discharge
method.
The Human Body Model has been the generally
acceptedESDtestingmethodforsemiconductors.
This method is also specified in MIL-STD-883,
Method 3015.7 for ESD testing. The premise of
this ESD test is to simulate the human body’s
potential to store electro-static energy and
discharge it to an integrated circuit. The
simulation is performed by using a test model as
shown in Figure 9. This method will test the
IC’s capability to withstand an ESD transient

With the Air Discharge Method, an ESD voltage
is applied to the equipment under test (EUT)
throughair. Thissimulatesanelectricallycharged
person ready to connect a cable onto the rear of
the system only to find an unpleasant zap just
before the person touches the back panel. The
high energy potential on the person discharges
through an arcing path to the rear panel of the
system before he or she even touches the system.
This energy, whether discharged directly or
through air, is predominantly a function of the
discharge current rather than the discharge
voltage. Variables with an air discharge such as
approach speed of the object carrying the ESD
potential to the system and humidity will tend to
change the discharge current. For example, the
rise time of the discharge current varies with the
approach speed.

voltage stored in the capacitor is then applied
throughRS, thecurrentlimitingresistor, ontothe
device under test (DUT). In ESD tests, the SW2
switch is pulsed so that the device under test
receives a duration of voltage.
The Contact Discharge Method applies the ESD
current directly to the EUT. This method was
devised to reduce the unpredictability of the
ESD arc. The discharge current rise time is
constant since the energy is directly transferred
without the air-gap arc. In situations such as
handheldsystems,theESDchargecanbedirectly

Forthe HumanBodyModel, the current limiting
resistor (R ) and the source capacitor (C ) are
1.5kΩ an 10S 0pF, respectively. For IEC-10S00-4-
2,thecurrentlimitingresistor(RS)andthesource
capacitor (CS) are 330Ω an 150pF, respectively.
The higher C value and lower RS value in the
IEC1000-4-2Smodel are more stringent than the
HumanBodyModel. Thelargerstoragecapacitor
injects a higher voltage to the test point when
SW2 is switched on. The lower current limiting
resistor increases the current charge onto the test
point.

the typical ESD testing circuit used for all three
methods. TheCS isinitiallychargedwiththeDC
