ISL32273EFBZ

Drivers, Receivers, Transceivers Overview

The ISL32273EFBZ is an RS-422/RS-485 interface integrated circuit manufactured by Renesas Electronics Corporation. It features a quad driver configuration with no receivers, operating within a supply voltage range of 3.0 V to 5.5 V. The device supports data rates up to 10 Mb/s and includes ±15 kV ESD protection on all pins. It is housed in a 16-lead Quad Flat No-Lead (QFN) package and operates across an extended temperature range from -40°C to +125°C.

Drivers, Receivers, Transceivers Feature Summary

• Quad differential driver architecture for high-speed serial communication
• Robust electrostatic discharge protection rated at ±15 kV
• Extended industrial temperature operation capability

Drivers, Receivers, Transceivers Applications

• Industrial automation control networks
• Building management systems requiring RS-422/RS-485 connectivity
• Data acquisition systems in harsh electromagnetic environments

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'FBZ' against official Renesas documentation to confirm the exact package type and tape/reel specifications. Confirm end-of-life status or obsolescence notices prior to procurement, as availability may be limited. Ensure compatibility with existing PCB footprints for the 16-lead QFN form factor.

Drivers, Receivers, Transceivers Selection Notes

Select this component when a quad-driver-only solution is required for RS-422 or RS-485 bus topologies. The absence of receivers distinguishes it from transceiver variants. Verify that the 10 Mb/s speed and ±15 kV ESD rating meet the specific environmental and performance requirements of the target application.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3227xE series of robust interface devices. It complements other members of the family that may include receiver channels or different packaging options. The series is designed for applications demanding high reliability and noise immunity in industrial settings.

Drivers, Receivers, Transceivers Replacement Considerations

Check for direct pin-compatible substitutes within the ISL3227x family, such as the ISL32272E or ISL32273EV variants, ensuring functional equivalence regarding driver count and ESD ratings.
