1.8V to 3.3V, Micro-Power, ±15kV ESD, +125°C, Slew
Rate Limited, RS-485/RS-422 Transceivers
ISL32600E, ISL32601E, ISL32602E, ISL32603E
The Intersil ISL32600E, ISL32601E, ISL32602E and
ISL32603E are ±15kV IEC61000 ESD protected, micro power,
wide supply range transceivers for differential communication.
The ISL32600E and ISL32601E operate with VCC ≥ 2.7V and
have maximum supply currents as low as 100µA with both the
transmitter (Tx) and receiver (Rx) enabled. The ISL32602E and
ISL32603E operate with supply voltages as low as 1.8V. These
transceivers have very low bus currents, so they present less
than a “1/8 unit load” to the bus. This allows more than 256
transmitters on the network, without violating the RS-485
specification’s 32 unit load maximum.
Features

• Low Supply Currents . . . . . . . ISL32601E, 100µA (Max) @ 3V

• Symmetrical Switching Thresholds for Less Duty Cycle
Distortion (See Figure 9)
Rx inputs feature symmetrical switching thresholds, and up to
65mV of hysteresis, to improve noise immunity and to reduce
duty cycle distortion in the presence of slow moving input
signals (see Figure 9). The Rx input common mode range is the
full -7V to +12V RS-485 range for supply voltages ≥ 3V.
• Up to 65mV Hysteresis for Improved Noise Immunity
• Data Rates from 128kbps to 460kbps
• Specified for +125°C Operation
• 1/8 Unit Load Allows up to 256 Devices on the Bus
Hot Plug circuitry ensures that the Tx and Rx outputs remain in
a high impedance state while the power supply stabilizes.
This transceiver family utilizes slew rate limited drivers, which
reduce EMI, and minimize reflections from improperly terminated
transmission lines, or unterminated stubs in multidrop and
multipoint applications.
• -7V to +12V Common Mode Input/Output Voltage Range
(VCC ≥ 3V)
• Half and Full Duplex Pinouts; Three State Rx and Tx Outputs
• 5V Tolerant Logic Inputs
• Tiny MSOP Packages Consume 50% Less Board Space
The ISL32600E and ISL32602E 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 Ld packages.
See Table 1 for a summary of each device’s features.

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.
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
-7V to +12V. RS-422 and RS-485 are intended for runs as 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.
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. The symmetrical ±200mV switching thresholds
