ACPL-M61U-000E

Overview

The ACPL-M61U-000E is a high-speed logic gate optocoupler manufactured by Broadcom Limited. It features a single channel with a data rate of 10 Mb/s and an isolation voltage of 3750 Vrms. The device utilizes a DC input type and provides an open collector, Schottky clamped output. Key electrical parameters include a maximum propagation delay of 75 ns for both low-to-high and high-to-low transitions, a forward current of 2 mA, and a forward voltage of 1.3 V. The output can handle a current of 50 mA per channel with a reverse voltage rating of 5 V.

Feature Summary

• High common-mode rejection capability designed for noisy environments
• Schottky-clamped output structure to minimize storage time and improve switching speed
• Wide operating temperature range suitable for industrial applications
• Small outline package design for space-constrained PCB layouts

Applications

• Isolated communication logic interfaces in industrial power systems
• Control circuits in factory automation equipment
• Signal transmission between microcontrollers and isolated power stages

Procurement Notes

Verify the specific suffix (e.g., -000E) against the Bill of Materials to ensure compatibility with required packaging and lead times. Confirm that the open-collector output configuration aligns with the downstream circuit requirements. Check RoHS compliance status if environmental regulations apply to the final assembly. Ensure the SOIC-5 package footprint matches the PCB design constraints before ordering.

Selection Notes

Select this component when a high-speed digital interface requires galvanic isolation with a push-pull or open-collector output drive. The 10 Mb/s data rate supports fast serial communication protocols. Consider the 3750 Vrms isolation rating for safety-critical applications. The Schottky clamp feature makes it suitable for applications requiring minimal propagation delay variation and fast turn-off times compared to standard logic outputs.

Part Context

This part belongs to the ACPL-M61x series of high-speed optocouplers from Broadcom. The series includes variants such as the ACPL-M61L and ACPL-M61M, which share similar performance characteristics but may differ in output configurations or packaging options. The M61U specifically denotes the open-collector output variant within this family, designed for versatile interfacing needs.

Replacement Considerations

Direct substitutes within the same family include ACPL-M61L-000E and ACPL-M61M-000E. Verify that the alternative part's output type (push-pull vs. open collector) matches the application requirements. Ensure the replacement maintains the same 10 Mb/s data rate and isolation voltage specifications.
