ISL32172E, ISL32272E, ISL32174E, ISL32179E

QUAD, ±16.5kV ESD Protected, 3.0V to 5.5V, Low Power, RS-422 Transmitters

The

ISL32172E, ISL32272E, ISL32174E,

and

ISL32179E

are

±16.5kV IEC61000-4-2 ESD protected, 3.0V to 5.5V powered,

QUAD transmitters for balanced communication using the RS-

422 standard. These drivers have very low output leakage

currents (±10µA), so they present a low load to the RS-422

bus.

The driver (Tx) outputs are tri-statable and incorporate a hot

plug feature to keep them disabled during power-up and

power-down. The ISL32172E and ISL32272E have a common

EN/EN, the ISL32174E has a two channel EN12/EN34, and the

ISL32179E has a versatile combination of individual and group

channel enables (see

Table 1).

Only the ISL32179E driver can be slew-rate limited, and only at

the data rate of 0.46Mbps. Drivers on the other versions are not

limited, so they can achieve 10Mbps or 32Mbps data rates. All

versions are offered in industrial and extended industrial

(-40°C to +125°C) temperature ranges.

The ISL32179E’s QFN package has a 50% smaller footprint

compared to the TSSOP. The ISL32179E also features a logic

supply pin (V

) that sets the switching points of the enable and

DI inputs to be compatible with a lower supply voltage in mixed

voltage systems. Two speed select pins allow the ISL32179E to

be configured for 460kbps, 10Mbps, or 32Mbps data rates.

Individual channel and group enable pins increase the

ISL32179E’s flexibility.
