ISL32275EIVZ-T

Overview

The ISL32275EIVZ-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 bus I/O pins and includes fail-safe outputs to ensure a high logic state when inputs are open or shorted. It is housed in a 16-lead TSSOP package with a narrow profile (4.40 mm width) and functions reliably across an extended temperature range of -40 °C to +85 °C.

Feature Summary

• Integrated quad receiver architecture supporting RS-422/RS-485 differential signaling standards
• Robust electrostatic discharge protection rated at ±15 kV on bus input/output pins
• Fail-safe output circuitry maintains a defined high logic level during input disconnection or short-circuit conditions

Applications

• Industrial automation networks requiring reliable multi-drop communication
• Building automation systems utilizing RS-485 bus topologies
• Data acquisition modules operating in electrically noisy environments

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm that the specific suffix matches the required TSSOP-16 package variant. Ensure compliance with RoHS directives and moisture sensitivity levels prior to soldering processes. Cross-reference datasheet revisions to validate pinout consistency and electrical characteristics against current design requirements.

Selection Notes

Select this component when a quad receiver configuration is necessary for half-duplex or full-duplex RS-485/RS-422 applications. It is suitable for designs requiring high ESD immunity without external protection components. Consider thermal management if multiple receivers operate simultaneously near maximum temperature limits. Verify that the 20 Mb/s speed capability aligns with system timing constraints.

Part Context

This part belongs to the ISL32275E family of interface ICs, which provides robust communication solutions for industrial environments. The series emphasizes durability through enhanced ESD ratings and fail-safe mechanisms. It complements other transceiver variants by offering dedicated receiver functionality in a compact surface-mount package, facilitating integration into space-constrained PCB layouts.

Replacement Considerations

ISL32275EIBZ-T: Offers identical electrical specifications but utilizes a SOIC-Narrow-16 package instead of TSSOP-16. Verify footprint compatibility before substitution.
