ISL32175EFBZ

Drivers, Receivers, Transceivers Overview

The ISL32175EFBZ is a quad RS-422/RS-485 transceiver manufactured by Renesas Electronics. It integrates four drivers and four receivers in a single package, supporting data rates up to 64 Mbps. The device operates on a single 3.0 V to 5.5 V power supply with a typical quiescent current of 800 µA. It features ±15 kV ESD protection on all pins and includes fail-safe circuitry to ensure a high logic state when inputs are open. The component is housed in a 16-lead Narrow SOIC package and supports an operating temperature range from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Integrates four differential drivers and four differential receivers for full RS-422/RS-485 communication capability.
• Provides robust ±15 kV human body model ESD protection across all signal pins.
• Incorporates fail-safe receiver design to maintain a high output state during input disconnection or short-circuit conditions.

Drivers, Receivers, Transceivers Applications

• Industrial automation control systems requiring reliable multi-drop communication.
• Building automation networks utilizing RS-485 bus topologies.
• Factory equipment interfaces demanding high ESD immunity and wide temperature operation.

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'EFBZ' against the manufacturer's latest datasheet to confirm package type and RoHS compliance status. Check for End-of-Life (EOL) notices or Product Change Notifications (PCN) as this series may have limited availability. Ensure sourcing channels provide valid traceability documentation for industrial applications.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad driver/receiver configuration is required for RS-422 or RS-485 networks. It is suitable for designs needing high-speed data transmission up to 64 Mbps with extended industrial temperature ranges. Consider alternative parts if lower pin counts or different packaging options are preferred for space-constrained layouts.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3217xE family of high-speed RS-422/RS-485 transceivers. The family shares common electrical characteristics but varies in package styles and thermal ratings. The ISL32175 variant specifically provides the quad driver/receiver functionality necessary for complex bus architectures in harsh environments.

Drivers, Receivers, Transceivers Replacement Considerations

Direct substitutes include other quad RS-422/RS-485 transceivers with similar 64 Mbps speeds and ±15 kV ESD ratings. Verify pin compatibility and voltage levels before replacing. Cross-reference with Renesas' recommended upgrades if the original part is discontinued.
