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.

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.

See Table 1 for a summary of each device’s features.
