ISL32453EIUZ-T7A

Drivers, Receivers, Transceivers Overview

The ISL32453EIUZ-T7A is a half-duplex RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It integrates one driver and one receiver within an 8-lead MSOP package. The device supports data rates up to 1 Mb/s and operates on supply voltages ranging from 3 V to 5.5 V. Key electrical specifications include a typical operating supply current of 4.5 mA and a receiver input hysteresis of 30 mV. It is designed for industrial environments with an extended operating temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Feature Summary

• Provides fault protection against overvoltages up to ±60 V on bus lines
• Ensures receiver output logic high state when inputs are floating or shorted
• Supports common mode voltage ranges up to ±20 V

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging configuration. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the 8-MSOP footprint matches the target PCB layout constraints. Validate that the ±60 V OVP rating meets the system's transient voltage requirements.

Drivers, Receivers, Transceivers Selection Notes

Select this component for applications requiring robust fault protection in noisy industrial environments. The 1 Mb/s data rate suits moderate-speed communication needs. Compare the ±20 V common mode range against other models if higher noise immunity is required. Verify thermal performance within the specified -40°C to +85°C operational window.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3245xE family of fault-protected transceivers. It shares architectural similarities with the ISL32455 and ISL32457 but differs in duplex capability and specific protection thresholds. The EIUZ suffix denotes the specific lead-free MSOP package variant offered by Renesas.

Drivers, Receivers, Transceivers Replacement Considerations

ISL32455EIUZ-T7A offers similar OVP protection but may differ in common mode range specifications. ISL32457EIBZ-T7A provides comparable functionality in an SOIC package. Verify pin compatibility and exact voltage ratings before substitution.
