ISL32173EIBZ-T

Overview

The ISL32173EIBZ-T is a high-speed RS-422/RS-485 receiver integrated circuit manufactured by Renesas Electronics Corporation. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 80 Mbps. The device features four receivers with a typical hysteresis of 30 mV for noise immunity. It is housed in a 16-pin SOIC package (SOIC-16) designed for surface mount technology. The component functions reliably across an extended industrial temperature range from -40°C to +85°C.

Feature Summary

• Supports high-speed serial communication protocols including RS-422 and RS-485 standards.
• Provides robust signal integrity through built-in receiver hysteresis to mitigate noise interference.
• Designed for low-voltage operation compatible with standard 3.3 V and 5 V logic systems.

Applications

• Industrial control systems requiring reliable multi-drop communication.
• Data acquisition networks utilizing RS-485 bus architectures.
• Embedded devices needing high-speed differential signaling receivers.

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration when sourcing. Confirm RoHS compliance status and moisture sensitivity level requirements against current project specifications. Ensure the supplier provides valid traceability documentation for this discontinued or legacy part number.

Selection Notes

Select this component specifically for applications requiring only receiver functionality without integrated drivers. Compare pinout compatibility with existing designs if replacing older Intersil variants. Validate that the 16-SOIC footprint matches the target PCB layout constraints and thermal management requirements.

Part Context

This part belongs to the ISL3217x family of interface ICs, which includes transceivers and receivers for RS-422 and RS-485 applications. The series is known for high-speed performance and ESD protection capabilities. It represents a transition product from the Intersil brand following its acquisition by Renesas Electronics.

Replacement Considerations

Publicly confirmed substitute part numbers include ISL32173EIBZ and ISL32173EFVZ. Verify package compatibility as the EFVZ variant uses a TSSOP housing instead of SOIC.
