ISL32453EIUZ-T

Drivers, Receivers, Transceivers Overview

The ISL32453EIUZ-T is a fully differential transceiver manufactured by Renesas Electronics Corporation, designed for RS-422 and RS-485 communication protocols. It features one driver and one receiver within a single package, supporting full-duplex operation with data rates up to 1 Mbps. The device operates on a supply voltage range of 3 V to 5.5 V and is housed in an 8-MSOP surface-mount package. It includes overvoltage protection (OVP) capabilities and maintains a receiver hysteresis of 30 mV to ensure noise immunity. The component is rated for an operating temperature range from -40°C to +85°C.

• Integrates overvoltage protection for enhanced line robustness
• Provides high noise immunity through defined receiver hysteresis

Drivers, Receivers, Transceivers Applications

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

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration. Confirm current availability status as the base model ISL32453EIBZ has been marked obsolete in public records. Ensure compliance with RoHS3 specifications and check for any recent Product Change Notices affecting assembly or material composition before finalizing procurement orders.

Drivers, Receivers, Transceivers Selection Notes

Select this component when full-duplex RS-422/RS-485 connectivity is required in space-constrained designs due to its compact MSOP footprint. Consider the 3 V to 5.5 V supply range compatibility with existing system power rails. Verify that the 1 Mbps data rate meets application timing requirements and that the -40°C to +85°C industrial temperature range aligns with environmental conditions.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3245xE family of OVP transceivers from Renesas. The family includes variants such as the ISL32453EIBZ and ISL32455EIUZ, which share similar core functionalities but differ in package types and duplex configurations. The ISL32453 specifically provides full-duplex capability, distinguishing it from half-duplex alternatives within the same product line.
