ISL32450EIUZ-T

Overview

The ISL32450EIUZ-T is a low-power RS-422/RS-485 transceiver manufactured by Renesas Electronics. It features a single driver and receiver, supporting data rates up to 1 Mbps. The device operates on a supply voltage range of 3 V to 5.5 V and functions within an industrial temperature range of -40°C to +85°C. It utilizes an MSOP-8 surface-mount package. Key electrical characteristics include 60 V overvoltage protection (OVP) on the bus pins and a common-mode rejection ratio (CMR) of 20 V. The component is RoHS compliant and part of the ISL3245xE series.

Feature Summary

• Integrated 60 V overvoltage protection on differential bus pins for enhanced system robustness
• High common-mode rejection capability of 20 V to ensure reliable signal integrity in noisy environments
• Low power consumption design with shutdown mode support for energy efficiency
• Compliant with RS-422 and RS-485 standards for versatile serial communication

Applications

• Industrial automation control systems requiring robust serial communication
• Building automation and security networks
• Process control instrumentation and monitoring devices
• Data acquisition systems operating in electrically noisy environments

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status through official manufacturer documentation or authorized distributor certificates. Check for recent Product Change Notifications (PCNs) regarding assembly or material changes. Ensure the supplier provides valid traceability records for quality assurance purposes prior to procurement.

Selection Notes

Select this component for applications requiring a single half-duplex transceiver with high noise immunity. The 60 V OVP feature makes it suitable for harsh industrial environments where transient voltages are present. Compare against other ISL3245x variants if different pin counts or full-duplex capabilities are required. Verify that the MSOP-8 package fits the available PCB footprint constraints.

Part Context

This part belongs to the ISL3245xE family of low-power RS-422/RS-485 transceivers from Renesas. The family includes various packages such as SOIC and TSSOP, and configurations like full-duplex models. The ISL32450 specifically denotes the half-duplex variant with one driver and one receiver. This series is designed to replace older Intersil components while offering improved performance metrics.

Replacement Considerations

Direct substitutes within the same family include ISL32450EIBZ (SOIC-14 package) and ISL32450EIUZ (MSOP-8 tube). Cross-reference with ISL32455E series for similar functionality but verify pinout compatibility. Ensure any replacement maintains the 60 V OVP rating and 1 Mbps speed requirement.
