ISL32173EFBZ-T

Drivers, Receivers, Transceivers Overview

The ISL32173EFBZ-T is an RS-422/RS-485 interface integrated circuit manufactured by Renesas Electronics Corporation. It functions as a quad receiver with zero drivers, designed for high-speed data communication. The device supports data rates up to 80 Mbps and operates within a supply voltage range of 3.0 V to 5.5 V. Key electrical specifications include a maximum operating current of 800 µA and robust electrostatic discharge (ESD) protection rated at ±15 kV. The component is housed in a 16-lead SOIC-Narrow package suitable for surface mount technology. It is engineered for reliable performance across an extended industrial temperature range from -40°C to +85°C.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix BZ-T against official Renesas documentation to confirm packaging format and tape-and-reel specifications. Confirm RoHS compliance status and moisture sensitivity level prior to procurement. Check for end-of-life notices or discontinuation announcements as availability may be limited. Ensure compatibility with existing PCB footprint requirements for the 16-SOIC package.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a dedicated quad receiver is required for RS-422 or RS-485 buses without integrated driver functionality. Consider the 80 Mbps speed limit and ±15 kV ESD rating for harsh industrial environments. Evaluate the 3.0 V to 5.5 V supply range against system power constraints. Compare thermal performance and package size against alternative receivers if space is limited.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3217xE family of high-speed transceivers from Renesas Intersil. It complements other variants like the ISL32172E which includes drivers.
