ISL3173EIUZ-T

Overview

The ISL3173EIUZ-T is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics Corporation. It operates on a single 3.3V supply and supports data rates up to 500kbps. The device features ±15kV IEC61000 ESD protection on the bus pins and >7kV HBM protection on other pins. It incorporates full fail-safe receiver functionality, ensuring a logic high output when inputs are floating or shorted. The component utilizes a 14-lead SOIC package and functions within an operating temperature range of -40°C to +85°C.

Feature Summary

• IEC61000 standard ESD protection on RS-485 I/O pins
• Full fail-safe receiver design for open or shorted bus conditions
• True 1/8 unit load capability supporting extensive network node counts

Applications

• Industrial automation control networks
• Building management systems
• Utility meter reading infrastructure

Procurement Notes

Verify current manufacturing status as this component may be subject to discontinuation notices. Confirm package availability and lead times through authorized distributors. Ensure compliance with RoHS3 specifications and check for any recent Product Change Notices affecting labeling or internal construction before finalizing procurement orders.

Selection Notes

Select this part for applications requiring robust ESD protection and reliable operation in electrically noisy environments. The 1/8 unit load characteristic allows for higher node density compared to standard 1/32 unit load devices. Verify that the 3.3V supply voltage aligns with the system power architecture and that the 500kbps speed meets communication requirements.

Part Context

This component belongs to the ISL317xE family of low-power, high-speed RS-485/RS-422 transceivers. The family shares common features such as hot-plug capability and thermal shutdown protection. The specific suffix indicates tape and reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

ISL3173EIBZ-T is a parameter-equivalent alternative from Renesas Electronics Corporation.
