ACPL-M61T-560E

Overview

The ACPL-M61T-560E is a high-speed logic output optocoupler manufactured by Broadcom Limited. It features a single channel with an open collector, Schottky-clamped output configuration. The device supports a data rate of 10 MBd and provides 3750 Vrms isolation voltage. Operating on a supply voltage range of 4.5V to 5.5V, it is housed in a surface-mount 5-SOIC package. Key electrical characteristics include a maximum DC forward current of 8 mA and an output current capability of 50 mA per channel.

Feature Summary

• Schottky-clamped open collector output design for enhanced switching performance
• High common-mode transient immunity (CMTI) for noise-resistant signal transmission
• Wide operating temperature range suitable for industrial environments

Applications

• Industrial automation control systems
• Power supply feedback loops
• Communication interface isolation

Procurement Notes

Verify the specific suffix '560E' to confirm the tape-and-reel packaging format and lead-free compliance status. Ensure the procurement order matches the required surface-mount quantity increments. Cross-reference the manufacturer part number with official Broadcom documentation to validate the open-collector output type against other variants in the ACPL-M61 series.

Selection Notes

Select this component when a push-pull output is not required, specifically utilizing its open-collector architecture for wired-OR configurations or level shifting. The 10 MBd speed rating makes it suitable for moderate-speed digital isolation. Verify that the system supply voltage falls within the 4.5V to 5.5V range and that the 50 mA output current capacity meets the load requirements.

Part Context

This device belongs to the ACPL-M61 family of high-speed optocouplers from Broadcom. While sibling models like the ACPL-M61M-560E offer push-pull outputs, the ACPL-M61T variant specifically utilizes an open-collector output structure. This distinction affects circuit design, particularly regarding pull-up resistor requirements and drive capabilities in isolated digital interfaces.

Replacement Considerations

Direct functional substitutes within the same family include the ACPL-M61M-560E, though it features a push-pull output rather than open-collector. Other ACPL-M61 variants may share the same package and isolation ratings but differ in output stage topology. Verify compatibility before substitution.
