ISL32452EIUZ-T7A

Overview

The ISL32452EIUZ-T7A is a half-duplex transceiver manufactured by Renesas Electronics Corporation, designed for RS-485 and RS-422 communication protocols. It integrates one driver and one receiver within an 8-MSOP surface-mount package. The device supports data rates up to 1 Mbps and operates on a single supply voltage ranging from 3V to 5.5V. Key electrical specifications include a receiver hysteresis of 30 mV and an operating temperature range spanning from -40°C to +85°C. The component features ±40V overvoltage protection on the bus pins and ±15kV ESD protection, ensuring robust performance in industrial environments.

Feature Summary

• Provides ±40V fault protection on the differential bus lines to safeguard against transient overvoltages.
• Supports common mode voltages up to ±15V, exceeding standard RS-485 requirements for noisy environments.
• Incorporates a full fail-safe receiver design that forces a high logic output when inputs are floating or shorted.

Applications

• Industrial automation control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 multi-drop configurations
• Metering equipment interfaces in utility infrastructure

Procurement Notes

Verify the specific suffix T7A indicates tape-and-reel packaging when sourcing components. Confirm RoHS3 compliance status through official manufacturer documentation prior to integration. Ensure the 8-MSOP footprint matches the target PCB layout dimensions accurately.

Selection Notes

Select this component for designs requiring 1 Mbps data throughput with enhanced bus protection capabilities. Compare against the ISL32432E series if lower cost is prioritized over higher voltage tolerance. Verify thermal management requirements for the MSOP package under maximum load conditions.

Part Context

This part belongs to the ISL3245xE family of fault-protected transceivers from Renesas. It shares functional similarities with the ISL32432E but offers improved overvoltage protection ratings. The T7A suffix specifically denotes the reel packaging format used for automated assembly processes.

Replacement Considerations

The ISL32432EIUZ-T7A is listed as a parameter-equivalent alternative. Verify pin compatibility and protection voltage levels before substitution. Other family members like ISL32455EIBZ may offer different package options.
