ISL32372EFVZ

Overview

The ISL32372EFVZ is a quad receiver integrated circuit manufactured by Renesas Electronics Corporation, belonging to the ISL3217xE series. Designed for RS-422 and RS-485 communication protocols, this component features four receivers within a single package. It operates on a supply voltage range of 3V to 5.5V and supports data rates up to 80Mbps. The device incorporates a 30mV hysteresis threshold to enhance noise immunity in noisy environments. It is housed in a 16-TSSOP surface-mount package with a width of 4.40mm and is rated for an operating temperature range from -40°C to +125°C.

Feature Summary

• Supports RS-422 and RS-485 differential communication standards
• Provides high noise immunity through 30mV receiver hysteresis
• Operates across extended industrial temperature ranges

Applications

• Industrial control systems requiring robust serial communication
• Multi-drop bus networks utilizing RS-485 protocols
• Data acquisition systems in electrically noisy environments

Procurement Notes

This component is officially designated as obsolete by the manufacturer. Production has ceased, and it is no longer available for new manufacturing orders. Verification of authenticity is critical when sourcing from secondary markets due to the high risk of counterfeit devices. Buyers must confirm the specific revision level and packaging type against original datasheets before procurement.

Selection Notes

Engineers should evaluate alternative components from current Renesas portfolios or other manufacturers offering equivalent RS-422/RS-485 quad receivers. Key selection criteria include matching the 80Mbps data rate, 3V-5.5V supply range, and TSSOP-16 footprint. Ensure that any replacement maintains compatibility with the existing system's electromagnetic interference requirements and thermal specifications.

Part Context

The ISL32372EFVZ is part of the Intersil-derived ISL3217xE family, which was integrated into Renesas' interface product line following corporate acquisitions. This series focuses on providing fault-protected and high-speed communication interfaces for demanding industrial applications. The specific model represents the quad-receiver variant within this broader ecosystem.
