ISL32455EIUZ-T7A

Drivers, Receivers, Transceivers Overview

The ISL32455EIUZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3.3 V to 5 V and supports data rates up to 1 Mb/s. The device features 60 V overvoltage protection (OVP) on the bus pins and a common-mode rejection capability of 20 V. It is housed in an 8-pin MSOP package with a shutdown function for power conservation. The component functions as a single driver and single receiver interface, operating reliably across a temperature range of -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 60 V overvoltage protection on differential bus pins
• High common-mode rejection ratio supporting noisy industrial environments
• Shutdown mode functionality for reduced power consumption

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor datasheets. Ensure the MSOP-8 package dimensions match the target PCB layout requirements before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection against high-voltage transients on RS-485 buses. The 1 Mb/s speed is suitable for moderate-distance communication where noise immunity is critical. Compare against standard transceivers if higher data throughput or different voltage levels are required.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32455E series of RS-485 transceivers designed for harsh electrical environments. The EIUZ designation specifies the extended temperature range and MSOP package variant. It serves as a reliable interface solution for serial communication in equipment exposed to potential electrical faults.
