ISL32435EIBZ-T7A

Overview

The ISL32435EIBZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 1 Mbps. The device features 40V overvoltage protection on both the transmit (TXD) and receive (RXD) pins, along with a common-mode rejection capability of 15V. It is housed in an 8-SOIC package and functions reliably across an industrial temperature range of -40°C to +85°C.

Feature Summary

• Integrated 40V overvoltage protection on driver and receiver inputs
• High common-mode rejection ratio for noise immunity
• Low power consumption with shutdown mode capability

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific suffix 'T7A' corresponds to the tape-and-reel packaging format required for automated assembly. Confirm that the SOIC-8 package variant matches the PCB footprint design. Ensure compliance with RoHS3 standards if environmental regulations apply to the final product deployment.

Selection Notes

Select this component when high-voltage fault tolerance is critical for bus line protection. The 1 Mbps speed suits moderate-distance communication needs. Compare against the ISL32432 series if lower cost or different pinout configurations are acceptable for the specific application constraints.

Part Context

This part belongs to the ISL3243xE family of RS-485 transceivers designed for robust communication in electrically noisy environments. The EIBZ designation indicates the SOIC-8 package version, distinguishing it from MSOP variants like the ISL32435EIUZ. It serves as a reliable interface between UARTs and differential bus lines.
