ISL32275EFVZ-T

Overview

The ISL32275EFVZ-T is a quad receiver integrated circuit from the Renesas ISL32275E series, designed for RS-422 and RS-485 communication interfaces. It operates within a supply voltage range of 3 V to 5.5 V and supports data rates up to 20 Mb/s. The device features ±15 kV ESD protection on all pins and is housed in a 16-pin TSSOP package with an exposed pad. It functions reliably across an extended industrial temperature range from -40°C to +125°C, drawing a typical operating supply current of 5.5 mA.

Feature Summary

• Provides four independent receivers compliant with RS-422 and RS-485 standards
• Features robust ±15 kV human body model ESD protection on all signal pins
• Supports high-speed data transmission at rates up to 20 Mb/s
• Operates over an extended industrial temperature range up to +125°C

Applications

• Industrial automation control systems requiring reliable serial communication
• Building automation networks utilizing RS-485 bus topologies
• Data acquisition systems interfacing with remote sensors
• Factory floor equipment connecting via differential signaling

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and moisture sensitivity level handling requirements prior to assembly. Review official discontinuance notifications as this specific part number may be subject to end-of-life status. Ensure packaging specifications match production line capabilities.

Selection Notes

Select this component when designing circuits requiring only receiver functionality for RS-422/RS-485 buses. Compare against full transceiver models if driver capability is also needed. Consider the 16-pin TSSOP footprint for PCB layout constraints. Verify that the 20 Mb/s speed meets system timing requirements and that the 3 V to 5.5 V supply range aligns with available power rails.

Part Context

This part belongs to the ISL32275E family of interface ICs manufactured by Renesas Electronics, formerly Intersil. The series includes variants such as the ISL32275EIBZ-T in SOIC packages and other temperature grades. These components are engineered for robust performance in electrically noisy environments common in industrial settings.

Replacement Considerations

Check for equivalent quad receiver parts from other manufacturers supporting RS-422/RS-485 with similar pinouts. Verify compatibility with existing board layouts and thermal management strategies. Ensure substitute components meet the same ±15 kV ESD protection and temperature range specifications.
