ISL3158EIUZ-T7A

Overview

The ISL3158EIUZ-T7A is a half-duplex RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates with a single 5 V supply and supports data rates up to 20 Mb/s. The device features high common-mode rejection, ESD protection compliant with IEC 61000 standards, and a shutdown mode for power conservation. It is housed in an MSOP-8 surface-mount package and functions within an industrial temperature range of -40°C to +85°C.

Feature Summary

• IEC 61000 ESD protection for robust operation in electrically noisy environments
• Shutdown mode significantly reduces quiescent current for energy efficiency
• High common-mode rejection ratio ensures reliable signal integrity

Applications

• Industrial automation control systems
• Building automation networks
• Metering infrastructure communication

Procurement Notes

Verify the specific suffix EIUZ-T7A against official Renesas documentation to confirm the MSOP-8 package and tape-and-reel orientation. Ensure compatibility with existing PCB footprints and reflow soldering profiles specified in the datasheet before procurement.

Selection Notes

Select this component when a 20 Mb/s data rate is required alongside strict ESD immunity requirements. Compare against the ISL3158EIBZ variant if an SOIC-8 package is preferred instead of the MSOP-8 form factor while maintaining identical electrical performance.

Part Context

This part belongs to the ISL315xE series of low-power RS-485/RS-422 transceivers. It shares core functionality with other members like the ISL3152E and ISL3155E but is optimized for higher speed applications up to 20 Mb/s within the same 5 V supply architecture.
