ACPL-021L-000E

Overview

The ACPL-021L-000E is a single-channel, low-power digital CMOS optocoupler manufactured by Broadcom Limited. It features a data rate of 5 MBd and an isolation voltage of 3750 Vrms. The device utilizes a push-pull, totem-pole output stage with a common mode transient immunity (CMTI) of 25 kV/µs. Electrical characteristics include a forward current of 2.2 mA, forward voltage of 1.5 V, rise time of 11 ns, and fall time of 11 ns. It operates within a temperature range of -40°C to 105°C and is available in an 8-SOIC surface-mount package.

Feature Summary

• Integrates a CMOS detector output stage for high-speed digital signal transmission.
• Provides robust noise immunity with a minimum common mode transient immunity of 25 kV/µs.
• Designed for low power consumption applications requiring high-speed logic isolation.

Applications

• Low isolation high-speed logic systems
• Industrial communication interfaces
• Ground isolation in noisy environments

Procurement Notes

Verify the specific ordering suffix to ensure compliance with RoHS directives and lead-free requirements. Confirm that the 8-SOIC package dimensions match the target PCB footprint. Ensure the selected variant meets the required operating temperature range of -40°C to 105°C for the intended application environment.

Selection Notes

Select this component when a single channel with 5 MBd speed and 3750 Vrms isolation is required. Compare against the ACPL-K24L-000E if dual-channel functionality or higher 5000 Vrms isolation is necessary. Consider the low power consumption and fast rise/fall times for efficient system design.

Part Context

The ACPL-021L series represents Broadcom's industrial-grade low-power digital optocouplers. This specific model is part of a family designed for high-speed data transfer while maintaining electrical isolation between circuits. It serves as a critical interface component in systems requiring reliable signal transmission across potential ground differences.

Replacement Considerations

The ACPL-K24L-000E is a verified dual-channel alternative offering similar speed but higher isolation voltage. Direct pin-compatible replacements should be verified against official datasheets to ensure identical electrical parameters and package dimensions before substitution.
