ISL32483EIBZ

Overview

The ISL32483EIBZ is a low-cost, half-duplex RS-485 transceiver manufactured by Renesas Electronics. It operates on a single 3V to 3.6V supply and supports data rates up to 250kbps. The device features a small SOIC-8 surface-mount package and includes thermal shutdown protection. It is designed for balanced digital communication lines in industrial environments.

Feature Summary

• Half-duplex operation with integrated driver and receiver
• Low power consumption suitable for battery-operated systems
• Thermal shutdown protection for enhanced reliability

Applications

• Industrial automation control networks
• Building automation systems
• Metering applications requiring RS-485 connectivity

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level prior to assembly. Check for obsolescence notices or lifecycle changes from the manufacturer before finalizing procurement plans.

Selection Notes

Select this component for designs requiring cost-effective RS-485 communication with limited voltage headroom. Ensure the application does not exceed the 250kbps data rate limit. Verify that the SOIC-8 footprint matches the PCB layout requirements and that the 3.6V maximum supply aligns with system power rails.

Part Context

This part belongs to the ISL834xx family of RS-485/RS-422 interface ICs. It shares functional similarities with other members like the ISL83485 but differs in specific electrical characteristics and pin configurations. It serves as a legacy option for standard baud rate communications.

Replacement Considerations

Direct substitutes include ISL83485EIBZ for higher speed capabilities or ISL32485EIBZ for extended fault protection. Verify pin compatibility and electrical specifications when migrating to newer generations within the Renesas portfolio.
