ISL32179EIRZ-T

Drivers, Receivers, Transceivers Overview

The ISL32179EIRZ-T is a quad RS-422 driver manufactured by Renesas Electronics Corporation, housed in a QFN-EP-24 surface-mount package. It operates on a supply voltage ranging from 3 V to 5.5 V with a maximum operating current of 800 uA. The component supports data rates up to 32 Mb/s and provides 15 kV ESD protection. It functions within an ambient temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides four independent differential drivers for RS-422 communication
• Features high electrostatic discharge protection rated at 15 kV
• Operates efficiently with low quiescent power consumption

Drivers, Receivers, Transceivers Applications
