Intersil ISL32179EIRZ

驱动器RS422，RS485

Overview

The ISL32172E, ISL32272E, ISL32174E, and ISL32179EIRZ 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 ISL32179E’s QFN package has a 50% smaller footprint compared to the TSSOP. The ISL32179EIRZ also 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 ISL32179EIRZ to be configured for 460kbps, 10Mbps, or 32Mbps data rates. Individual channel and group enable pins increase the ISL32179E’s flexibility.
