ISL32740EFBZ-T7A

Drivers, Receivers, Transceivers Overview

The ISL32740EFBZ-T7A is a high-speed, galvanically isolated RS-485 differential bus transceiver manufactured by Renesas Electronics Corporation. It integrates an RS-485 driver and receiver with a digital isolator to provide robust communication in noisy industrial environments. The device supports data rates up to 10 Mb/s and operates within a supply voltage range of 3 V to 5.5 V. It features a half-duplex architecture with one driver and one receiver. Key electrical specifications include a maximum output current of 60 mA and an operating power consumption of approximately 4 mA. The component is rated for extended industrial temperatures from -40°C to +85°C and includes 15 kV ESD protection on the I/O pins.

Drivers, Receivers, Transceivers Feature Summary

• Galvanic isolation between the logic side and the bus side prevents ground loops and protects sensitive circuitry from high-voltage transients.
• High-speed data transmission capability supports baud rates up to 10 Mb/s for efficient real-time communication.
• Integrated overtemperature shutdown and fail-safe receiver circuits ensure reliable operation under fault conditions.

Drivers, Receivers, Transceivers Applications

• Industrial automation systems requiring noise-immune serial communication
• Factory floor control networks connecting PLCs and sensors
• Building automation and HVAC control systems

Drivers, Receivers, Transceivers Procurement Notes

Verify the specific suffix 'FBZ' against the manufacturer's latest datasheet to confirm package type and tape/reel specifications. Confirm RoHS compliance status directly with Renesas or authorized distributors as regulatory requirements may vary by region. Check for obsolescence notices or lifecycle changes before finalizing procurement plans.

Drivers, Receivers, Transceivers Selection Notes

Select this component when high-speed (10 Mb/s) isolated RS-485 communication is required in electrically noisy environments. Ensure the design accommodates the QSOP-16 package dimensions if space is constrained. Verify that the system voltage matches the 3 V to 5.5 V input range and that the load does not exceed the 60 mA output current limit.

Drivers, Receivers, Transceivers Part Context

This part belongs to the ISL3274xE series of isolated RS-485 transceivers. It shares functional similarities with the ISL32741E but differs in pinout configuration and specific isolation barrier ratings. The series is designed to replace traditional optocoupler-based solutions with higher performance and lower power consumption.

Drivers, Receivers, Transceivers Replacement Considerations

Direct replacements are limited due to unique isolation architectures. Consider the ISL32741EFBZ-T7A for similar functionality with different pinouts. Verify compatibility with existing PCB footprints and isolation voltage requirements before substituting.
