ISL32274EIBZ

Overview

The ISL32274EIBZ is a quad receiver interface integrated circuit manufactured by Renesas Electronics Corporation, belonging to the ISL3227xE series. Designed for RS-422 and RS-485 communication standards, this component features four receivers within an 8-pin SOIC package. It operates on a single 5V supply voltage with a maximum data rate of 20 Mb/s. The device supports an operating temperature range from -40°C to +85°C and includes overvoltage protection on the receiver inputs.

Feature Summary

• Provides four independent high-speed receivers for differential bus applications
• Features robust input protection against electrostatic discharge and bus fault conditions
• Supports standard RS-422 and RS-485 communication protocols

Applications

• Industrial automation control systems
• Building automation networks
• Data acquisition modules

Procurement Notes

Verify the specific suffix 'EIBZ' corresponds to the lead-free tape-and-reel packaging variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to integration. Ensure the ordering quantity matches the required reel specifications for surface-mount assembly processes.

Selection Notes

Select this component when a design requires multiple receiver channels in a minimal footprint without transmitting capabilities. Compare pinout compatibility with existing designs if substituting from other quad receiver families. Validate that the 20 Mb/s speed meets the system's timing requirements.

Part Context

This part is part of the ISL3227xE family of high-speed RS-422/RS-485 transceivers. It complements driver-only or full-duplex variants within the same product line, offering a specialized solution for receive-heavy network topologies in industrial environments.
