ISL32450EIBZ

Overview

The ISL32450EIBZ is a full-duplex transceiver supporting RS-422 and RS-485 communication protocols. It operates within a supply voltage range of 3V to 5.5V and supports data rates up to 250kbps. The device features a receiver with 30mV hysteresis for noise immunity. It is housed in a 14-SOIC package (0.154 inch width) designed for surface mount installation. The component functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Supports full-duplex RS-422 and RS-485 interface standards
• Integrated receiver hysteresis enhances signal integrity in noisy environments
• Operates on standard single-supply voltages between 3V and 5.5V

Applications

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

Procurement Notes

Verify current availability status as the part is marked as obsolete. Confirm final procurement details directly with Renesas Electronics Corporation or authorized distributors, as lead times and stock levels are subject to change. Ensure compliance with RoHS3 specifications and check for any relevant Product Change Notices affecting assembly or material composition before ordering.

Selection Notes

Select this component for applications requiring robust full-duplex communication over moderate distances. The 14-SOIC package suits designs needing space-efficient surface mounting. Verify that the required data rate does not exceed 250kbps and that the operating environment stays within the specified temperature limits. Consider the obsolete status when planning long-term production lifecycles.

Part Context

This device belongs to the ISL3245x family of overvoltage protection transceivers from Renesas. These components are engineered for reliable serial communication in electrically noisy industrial settings. The specific model provides full-duplex capabilities, distinguishing it from half-duplex variants within the broader product line.

Replacement Considerations

As the ISL32450EIBZ is obsolete, consult official Renesas documentation for qualified replacement parts. Evaluate alternative transceivers based on pin compatibility, protocol support, and package dimensions to ensure seamless integration into existing designs.
