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
Features
ISL32603E are ±15kV IEC61000 ESD protected, micro power,
wide supply range transceivers for differential communication.
The ISL32600E and ISL32601E operate with V
CC
≥
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.
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.
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.
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.

FUNCTION
Receiver output: If A-B
≥
200mV, RO is high; If A-B
≤
-200mV, RO is low; RO = High if A and B are unconnected
(floating).
Receiver output enable. RO is enabled when RE is low; RO is high impedance when RE is high. If the Rx enable
function isn’t required, connect RE directly to GND.
Driver output enable. The driver outputs, Y and Z, are enabled by bringing DE high, and are high impedance
when DE is low. If the Tx enable function isn’t required, connect DE to V
CC
.
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.
Ground connection.

output. Pin is an input if DE = 0; pin is an output if DE = 1.
