ISL32450EIUZ

Overview

The ISL32450EIUZ is a full-duplex RS-422 and RS-485 transceiver manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 250kbps. The device features an extended common-mode input range from -20V to +20V and includes overvoltage protection on the bus pins. It is housed in a 10-lead MSOP surface-mount package and is rated for operation across a temperature range of -40°C to +85°C.

Feature Summary

• Supports full-duplex communication protocols including RS-422 and RS-485 standards
• Provides fault protection with overvoltage tolerance on differential bus pins
• Features an extended common-mode range capable of handling high noise environments

Applications

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

Procurement Notes

Verify component authenticity through authorized channels as this part may be obsolete or subject to lifecycle changes. Confirm that the specific suffix matches the required package type and thermal rating. Check for available parametric equivalents if original stock is unavailable. Ensure compliance with RoHS3 specifications and verify moisture sensitivity levels prior to soldering processes.

Selection Notes

Select this transceiver when full-duplex operation is required for RS-422 or RS-485 applications. Choose based on the need for extended common-mode range and overvoltage protection in noisy industrial environments. Consider the MSOP package size constraints and the 3V to 5.5V operating voltage range relative to system power supplies.

Part Context

This component belongs to the ISL3245xE family of fault-protected, extended common-mode range differential transceivers designed for balanced communication buses. These devices are engineered to provide reliable signal transmission in harsh electrical environments while maintaining compatibility with standard serial communication protocols.
