ISL3170EIBZ-T7A

Overview

The ISL3170EIBZ-T7A is a single RS-485/RS-422 transceiver manufactured by Renesas Electronics. It operates on a single 3.3V supply and supports data rates up to 250 kbps. The device features ±15kV IEC61000 ESD protection, full fail-safe receivers, and true 1/8 unit load capability for up to 256 nodes. It utilizes an SOIC-8 package with a -40°C to +85°C operating temperature range.

Feature Summary

• IEC61000 ESD protection on RS-485 I/O pins
• Full fail-safe receiver design
• True 1/8 unit load bus loading

Applications

• Remote utility meter reading systems
• Industrial automation networks
• Building control systems

Procurement Notes

Verify the specific suffix T7A indicates tape and reel packaging when sourcing. Confirm RoHS compliance status through official documentation. Ensure the supplier provides valid traceability records for quality assurance purposes.

Selection Notes

Select this component for applications requiring low node count flexibility and robust ESD protection. Verify that the 250 kbps speed meets system requirements. Check if the SOIC-8 footprint fits the PCB layout constraints.

Part Context

This part belongs to the ISL317xE series of low-power, high-speed RS-485/RS-422 transceivers. It shares core architectural features with other members like the ISL3172E but differs in specified data rate limits and package options within the broader product family.

Replacement Considerations

ISL3170EIBZ is the non-tape-and-reel equivalent. ISL3172EIBZ offers higher speed capabilities. Verify pin compatibility before substitution.
