ISL32435EIUZ

Drivers, Receivers, Transceivers Overview

The ISL32435EIUZ is a half-duplex RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0 V to 5.5 V and supports data rates up to 1 Mb/s. The device features 40 V overvoltage protection on the I/O pins and a common-mode rejection capability of 15 V. It functions reliably across an extended temperature range from -40°C to +125°C. The unit is housed in an 8-lead MSOP package with a typical operating supply current of 4.5 mA.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 40 V overvoltage protection on receiver inputs and transmitter outputs for enhanced robustness
• High common-mode rejection ratio of 15 V to ensure signal integrity in noisy environments
• Extended thermal stability supporting operation up to +125°C junction temperature

Drivers, Receivers, Transceivers Applications

• Industrial automation bus systems requiring high noise immunity
• Building automation networks utilizing RS-485 or RS-422 protocols
• Metering applications involving multi-drop communication lines

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix against official Renesas documentation to confirm pinout compatibility and electrical specifications. Ensure the procurement channel provides valid RoHS compliance certificates. Confirm that the MSOP-8 package dimensions match the target PCB footprint requirements before finalizing orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when designs require integrated overvoltage protection without external clamping diodes. It is suitable for applications needing operation at elevated temperatures up to 125°C. Consider the 1 Mb/s data rate limit and half-duplex architecture when evaluating system throughput requirements against alternative full-duplex options.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3243xE series of low-power RS-485/RS-422 transceivers. The series emphasizes ruggedness through built-in overvoltage protection and high common-mode rejection. It serves as a bridge between microcontroller UARTs and balanced differential transmission lines in industrial settings.
