ISL32432EIBZ-T

Overview

The ISL32432EIBZ-T is a half-duplex transceiver manufactured by Renesas Electronics Corporation, designed for RS-422 and RS-485 communication protocols. It integrates one driver and one receiver within an 8-MSOP surface-mount package. The device supports data rates up to 250 kbps and operates on a single 3V to 5.5V power supply. Key electrical specifications include a receiver input hysteresis of 30 mV and a common mode rejection capability handling voltages up to ±15V. The component is rated for industrial operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Provides ±40V fault protection on driver outputs to safeguard against overvoltage conditions
• Features ±15kV ESD protection on all pins to enhance reliability in harsh environments
• Incorporates a full fail-safe receiver design that ensures a logic high output when inputs are floating or shorted

Applications

• Industrial automation control systems requiring robust serial communication
• Building automation networks utilizing RS-485 bus topologies
• Factory equipment interfaces needing high noise immunity and fault tolerance

Procurement Notes

Verify the specific suffix 'BZ' against official Renesas documentation to confirm the exact package type and tape/reel configuration. Ensure the ordering part number matches the required temperature grade and packaging format for your manufacturing process. Cross-reference with the manufacturer's latest datasheet to confirm current production status and any recent product change notices affecting labeling or materials.

Selection Notes

Select this component when designing circuits that require half-duplex RS-485 communication with enhanced fault protection capabilities. The 8-MSOP package is suitable for space-constrained applications. Verify that the 250 kbps data rate meets system requirements and that the 3V to 5.5V supply range aligns with the target voltage rails. Consider the ±40V output protection if the application involves long cable runs or potential exposure to induced surges.

Part Context

This part belongs to the ISL3243xE series of fault-protected transceivers from Renesas. The series shares similar core functionalities but varies in package options and specific pin configurations. The 'ISL32432' designation specifically indicates a half-duplex unit with one driver and one receiver, distinguishing it from full-duplex variants like the ISL32430E or multi-driver versions within the same family.
