ISL32173EIBZ

Overview

The ISL32173EIBZ is a quad receiver integrated circuit designed for RS-422 and RS-485 communication protocols. Manufactured by Renesas Electronics Corporation, this component operates within a supply voltage range of 3V to 5.5V and supports data rates up to 80Mbps. It features a receiver hysteresis of 30mV to enhance noise immunity in noisy environments. The device is housed in a 16-SOIC package with a width of 3.90mm and is rated for an operating temperature range of -40°C to +85°C. It complies with RoHS3 standards and has a Moisture Sensitivity Level (MSL) of 3.

Feature Summary

• Provides four independent receivers for differential signal conversion
• Supports high-speed data transmission up to 80Mbps
• Includes 30mV hysteresis for improved noise rejection
• Compatible with standard RS-422 and RS-485 bus topologies

Applications

• Industrial control systems requiring robust serial communication
• Building automation networks utilizing RS-485 buses
• Data acquisition systems in harsh electrical environments
• Factory automation equipment interfaces

Procurement Notes

Verify the specific suffix 'IBZ' against the manufacturer's current datasheet to confirm package dimensions and tape-and-reel specifications. Ensure the procurement channel provides valid traceability documentation for RoHS3 compliance. Cross-reference the MSL rating of 3 with your facility's storage and reflow soldering procedures to prevent moisture-induced damage during assembly.

Selection Notes

Select this component when only receiving functionality is required for RS-422 or RS-485 applications. Compare the 80Mbps speed and 30mV hysteresis against alternative quad receivers if higher noise immunity or different voltage levels are needed. Confirm that the 16-SOIC footprint matches the existing PCB layout constraints before finalizing the design choice.

Part Context

This part belongs to the ISL32173 family of interface ICs, which includes variants with different packages such as the EFVZ (TSSOP). The base model number ISL32173 denotes a quad receiver configuration. Other family members may include transceivers with integrated drivers, whereas this specific variant focuses solely on the reception side of the communication link.

Replacement Considerations

The ISL32173EFVZ serves as a pin-compatible alternative offering the same electrical characteristics but utilizes a 16-TSSOP package instead of the SOIC form factor. Verify board space availability for the TSSOP width change before substituting.
