ISL32455EIUZ-T

Drivers, Receivers, Transceivers Overview

The ISL32455EIUZ-T is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 3 V to 5.5 V supply and supports data rates up to 1 Mbps. The device features a 60 V overvoltage protection (OVP) on the I/O pins and a common-mode rejection ratio of 20 V. It is housed in an 8-pin MSOP package and functions within a temperature range of -40 °C to +85 °C.

Drivers, Receivers, Transceivers Feature Summary

• Integrated 60 V overvoltage protection on I/O pins for enhanced bus safety
• High common-mode rejection capability supporting noisy industrial environments
• Single-supply operation compatible with standard 3 V and 5 V logic levels

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems
• Building automation networks
• Data communication equipment

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when sourcing. Confirm RoHS compliance status through official datasheets or manufacturer documentation prior to integration. Ensure the component matches the exact MSOP-8 footprint requirements for the target PCB design.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust I/O protection against transient voltage events. The 1 Mbps speed rating suits moderate-speed serial communication needs. Verify that the 3 V to 5.5 V supply range aligns with the system's power architecture and that the half-duplex configuration meets the bidirectional data flow requirements.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL32455E series of RS-422/RS-485 interface ICs from Renesas. It is designed for reliable communication in electrically noisy environments, offering a balance of performance and protection features typical of industrial-grade interface solutions.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible alternatives within the same Renesas family that may offer updated packaging or minor parameter variations. Ensure any substitute maintains the 60 V OVP specification and 1 Mbps data rate to preserve system functionality.
