ISL32450EIBZ-T7A

Overview

The ISL32450EIBZ-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-pin SOIC package. The device supports data transmission rates up to 1 Mb/s and operates on a single 5 V supply voltage. It features overvoltage protection rated at 60 V on the bus pins and a common-mode rejection capability of 20 V. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Integrated overvoltage protection for robust operation in electrically noisy environments
• High common-mode rejection ratio ensuring signal integrity under severe noise conditions
• Shutdown mode functionality designed to minimize power consumption during idle periods

Applications

• Industrial automation control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 bus topologies
• Process control instrumentation with high noise immunity requirements

Procurement Notes

Verify authenticity through authorized distributors as this component may be subject to obsolescence notices. Confirm that the specific suffix matches the required tape-and-reel packaging format. Ensure compliance with current RoHS directives before integration into final assemblies.

Selection Notes

Select this part when a single half-duplex channel is sufficient for the application design. Compare against full-duplex alternatives if simultaneous bidirectional communication is necessary. Verify that the 5 V logic interface aligns with the system's microcontroller or processor voltage levels.

Part Context

This component belongs to the ISL3245xE family of high-voltage protected transceivers. It shares core architectural similarities with other members like the ISL32455, differing primarily in pinout configurations and specific electrical tolerances defined by the manufacturer for distinct deployment scenarios.

Replacement Considerations
