Overview

DATASHEET ISL32172E, ISL32272E, ISL32174E, ISL32179E QUAD, ±16.5kV ESD Protected, 3.0V to 5.5V, Low Power, RS-422 Transmitters FN6824 Rev 4.01 Mar 19, 2020 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 RS422 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.

Key Features

  • a logic supply pin (VL) 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.
