ISL32275EIBZ-T

Overview

The ISL32275EIBZ-T is a quad receiver integrated circuit belonging to the RS-422/RS-485 interface family, manufactured by Renesas Electronics. Designed for surface-mount applications in SOIC-Narrow-16 packages, this component supports data transmission rates up to 20 Mb/s. It operates within a supply voltage range of 3 V to 5.5 V and features robust electrostatic discharge protection rated at +/-15 kV. The device functions reliably across an extended industrial temperature range from -40°C to +85°C, drawing a typical operating supply current of 5.5 mA.

Feature Summary

• Integrates four independent receivers for high-density differential signaling applications.
• Provides enhanced fault tolerance with +/-15 kV ESD protection on all pins.
• Supports high-speed data communication up to 20 Mb/s over RS-422 and RS-485 networks.

Applications

• Industrial automation control systems requiring multi-drop bus connectivity.
• Building automation and security network interfaces.
• Data acquisition systems utilizing RS-485 communication protocols.

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to end-of-life status. Confirm package integrity and moisture sensitivity level handling procedures upon receipt. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before procurement integration.

Selection Notes

Select this component when designing circuits requiring four simultaneous receiver channels on a single IC. Ensure the application environment stays within the specified -40°C to +85°C operational temperature limits. Verify that the system power supply remains stable between 3 V and 5.5 V to maintain signal integrity and proper logic threshold performance.

Part Context

This part belongs to the ISL32275E series of RS-422/RS-485 interface devices. It serves as a specialized receiver-only solution within the broader Renesas portfolio of industrial communication components. The suffix 'T' indicates tape-and-reel packaging suitable for automated surface-mount assembly processes.

Replacement Considerations

The component is listed as discontinued. Potential substitutes include other quad receiver ICs from the same manufacturer or compatible third-party RS-485 receivers. Verify pinout compatibility and electrical parameters before substitution.
