ACPL-M21L-560E

Overview

The ACPL-M21L-560E is a single-channel high-speed optocoupler from the Broadcom ACPL series, designed for robust signal isolation in demanding electronic environments. It features a push-pull output configuration with a data rate of 5 Mb/s and an isolation voltage of 3750 Vrms. The device operates within a temperature range of -40°C to +105°C and utilizes a 5-pin SOIC surface-mount package. Key electrical parameters include a typical rise/fall time of 11 ns, a forward current of 8 mA, and a forward voltage of 2V.

Feature Summary

• Push-pull output stage provides strong drive capability and fast switching performance.
• High common-mode transient immunity ensures reliable operation in noisy environments.
• Wide operating temperature range supports industrial and automotive applications.

Applications

• Industrial automation control systems
• Power supply feedback loops
• Data communication interfaces requiring galvanic isolation

Procurement Notes

Verify component authenticity through authorized distributors or official manufacturer channels. Confirm that the part number suffix matches the required insulation voltage and package variant. Request relevant certification documents such as UL, IEC, and CSA compliance records to ensure adherence to safety standards for your specific application requirements.

Selection Notes

Select this component when a single channel with push-pull output is required for high-speed digital isolation. Ensure the system voltage does not exceed the specified isolation rating. Consider the thermal management capabilities given the wide operating temperature range and surface-mount packaging constraints during PCB layout design.

Part Context

This device belongs to the ACPL series of high-speed optocouplers manufactured by Broadcom Limited. The series is engineered for applications requiring fast signal transmission across isolation barriers while maintaining electrical safety. The ACPL-M21L-560E specifically targets markets needing reliable isolation with moderate data rates and robust noise immunity.

Replacement Considerations

Direct replacements must match the 5-SO package, 5 Mb/s data rate, and 3750 Vrms isolation voltage. Verify pinout compatibility and electrical characteristics before substitution. Consult official replacement guides for cross-reference options within the same product family.
