ISL32173E, ISL32175E, ISL32177E, ISL32273E, ISL32275E,

ISL32277E

These Intersil devices are ±16.5kV IEC61000-4-2 ESD

protected, 3.0V to 5.5V powered, quad receivers for balanced

communication using the RS-485 and RS-422 standards. Each

receiver has low input currents (±200µA), so it presents a 1/4

unit load to the RS-485 bus and allows up to 128 receivers on

the bus.

The

ISL32173E, ISL32175E, ISL32177E

are high data rate

receivers that operate at data rates up to 80Mbps. Their 8ns

maximum propagation delay skew (tolerance) guarantees

excellent part-to-part matching. The

ISL32273E, ISL32275E,

ISL32277E

are reduced supply current versions that operate at

data rates up to 20Mbps.

Receiver outputs are tri-statable and incorporate a hot plug

feature to keep them disabled during power-up and

power-down. Versions are available with a common EN/EN

(ISL32173E pinout), a two channel EN12/EN34 (ISL32175E

pinout), or a vers atile individual channel enable (see

Table 1).

A 26% smaller footprint is available with the ISL32177E and

ISL32277E QFN packages and these two devices also feature

a logic supply pin (V

). The V

supply sets the switching points

of the enable inputs and the receiver outputs’ V

, to levels

compatible with a lower supply voltage in mixed voltage

systems. Individual channel and group enable pins increase

the ISL32177E and ISL32277E’s flexibility.
