ISL32174EIBZ-T

Overview

The ISL32174EIBZ-T is a quad receiver RS-422/RS-485 interface integrated circuit manufactured by Renesas Electronics. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 80 Mbps. The device provides robust protection against electrostatic discharge, rated at +/-15kV. Designed for surface-mount applications, it is housed in a 16-lead SOIC package. The component functions exclusively as a receiver without integrated drivers, making it suitable for half-duplex or full-duplex bus configurations requiring high-speed signal reception in industrial environments.

Feature Summary

• High-speed data reception capability supporting up to 80 Mbps transmission rates
• Integrated electrostatic discharge protection rated at +/-15kV on input pins
• Compatible with standard 3.0V to 5.5V power supply rails
• Surface-mount packaging optimized for automated assembly processes

Applications

• Industrial communication networks utilizing RS-422 or RS-485 protocols
• Multi-drop bus systems requiring high-speed signal integrity
• Embedded control units in noisy electrical environments

Procurement Notes

Verify the specific suffix EIBZ-T against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with existing PCB footprints for the 16-lead SOIC format. Cross-reference RoHS compliance status with the latest environmental declarations provided by Renesas Electronics prior to finalizing procurement orders.

Selection Notes

Select this component when only receiver functionality is required for RS-422/RS-485 buses. It is appropriate for designs needing 80 Mbps throughput and strong ESD immunity. Consider alternative parts if driver integration or lower data rates are sufficient for the application requirements.

Part Context

This part belongs to the ISL3217x series of interface ICs from Renesas, which focuses on reliable serial communication in harsh conditions. The series typically includes variants with varying numbers of receivers and drivers. The ISL32174 specifically isolates the receiving function to support flexible bus topology designs in industrial automation sectors.

Replacement Considerations

Check for direct pin-compatible substitutes within the same ISL3217x family that may offer different receiver counts. Verify equivalent performance metrics such as data rate and ESD ratings before substituting with components from other manufacturers.
