ISL32430EIUZ-T

Overview

The ISL32430EIUZ-T is an RS-422/RS-485 interface transceiver manufactured by Renesas Electronics. 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 the bus pins and offers common-mode rejection of 15V. It functions reliably across an extended temperature range from -40°C to +85°C. The component is housed in an 8-lead MSOP package, designed for surface-mount applications.

Feature Summary

• Integrated 40V overvoltage protection on differential bus pins
• High common-mode rejection capability of 15V
• Supports full-duplex RS-422 and half-duplex RS-485 communication protocols
• Operates with a wide single-supply voltage range

Applications

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

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm RoHS compliance status through official datasheets as regulatory requirements may vary by region. Check for end-of-life notifications or discontinuance notices from Renesas to ensure long-term availability for production planning.

Selection Notes

Select this component when 40V fault protection is required on RS-485/RS-422 buses. Ensure the 1 Mbps speed meets system timing requirements. Verify that the 8-lead MSOP package fits the PCB layout constraints. Compare against other ISL3243x variants if different pin counts or protection levels are needed.

Part Context

This part belongs to the ISL3243xE family of high-performance, low-power RS-422/RS-485 transceivers. The series is characterized by robust fault protection and high noise immunity. It is designed for demanding industrial environments where signal integrity and pin protection are critical.

Replacement Considerations

Check for direct pin-compatible replacements within the ISL3243x family. Verify electrical parameters such as data rate and operating voltage match exactly. Consider newer Renesas interface ICs if the current part is discontinued.
