ISL32177EFRZ-T

Overview

The ISL32177EFRZ-T is a quad RS-422/RS-485 transceiver manufactured by Renesas Electronics Corporation. It supports data rates up to 64 Mbps and operates within a supply voltage range of 3 V to 5.5 V. The device features ±15 kV ESD protection on the bus pins, ensuring robust performance in electrically noisy environments. It is housed in a 24-lead QFN package with an exposed pad for improved thermal dissipation. The component functions across an extended industrial temperature range from -40°C to +125°C.

Feature Summary

• Integrated high-level electrostatic discharge (ESD) protection on all bus lines to safeguard against transient events.
• Supports high-speed differential communication protocols including RS-422 and RS-485 standards.
• Designed for reliable operation in harsh industrial environments with wide temperature tolerance.

Applications

• Industrial automation control systems
• Building automation networks
• Process control instrumentation

Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when placing orders. Confirm the RoHS compliance status and lead-free finish details directly with the manufacturer or authorized distributors prior to procurement. Ensure the ordering quantity matches the required reel specifications to avoid handling discrepancies.

Selection Notes

Select this component for applications requiring quad transceivers with integrated ESD protection. Verify that the 64 Mbps data rate meets system requirements. Ensure the PCB layout accommodates the 24-lead QFN package dimensions and provides adequate thermal relief for the exposed pad to maintain junction temperatures within safe limits during operation.

Part Context

This part belongs to the ISL3217xE family of high-speed RS-422/RS-485 transceivers. It shares functional similarities with other members like the ISL32179E but differs in pinout and specific feature sets. The family is designed for robust serial communication in industrial settings where signal integrity and noise immunity are critical.

Replacement Considerations

Check for direct pin-compatible substitutes within the ISL3217xE series. Verify electrical parameters such as data rate and ESD ratings match the original design requirements before substituting.
