ACFL-6212U-000E

Overview

The Broadcom ACFL-6212U-000E is a dual-channel high-speed optocoupler featuring push-pull outputs. It operates within a supply voltage range of 3V to 5.5V and supports a data rate of 15 Mb/s. Key electrical parameters include a maximum forward current of 20 mA, a typical forward voltage of 1.5 V, and an output current of 10 mA per channel. The device provides 5000 Vrms isolation voltage and exhibits a common-mode transient immunity of 25 kV/µs. Propagation delays are typically 100 ns, with rise and fall times of 10 ns. It functions reliably across an extended temperature range from -40°C to +125°C.

Procurement Notes

Verify the specific suffix (e.g., -560E vs -000E) against the manufacturer's datasheet to ensure correct packaging and reel specifications. Confirm RoHS compliance status and moisture sensitivity level requirements prior to ordering. Cross-reference the supplier's component description with official Broadcom documentation to validate pinout compatibility and functional equivalence for your specific circuit design.

Selection Notes

Select this component when bi-directional data transfer requires high-speed isolation with robust noise immunity. The push-pull output architecture ensures strong drive capability for downstream logic circuits. Ensure the system voltage aligns with the 3V to 5.5V supply range. Verify that the 5000 Vrms isolation rating meets the safety standards required for the application's input-output separation needs.

Part Context

This device belongs to the R²Coupler series from Broadcom Limited. It is designed as a high-performance solution for isolating digital signals in electrically noisy environments. The SO-12 package facilitates surface-mount assembly. It serves as a specialized alternative to standard logic gate optocouplers where speed and bidirectional functionality are critical constraints.

Replacement Considerations

Check for direct substitutes within the ACFL-6212U family. Verify pin-to-pin compatibility and identical electrical characteristics before substituting. Ensure any replacement maintains the same isolation voltage and CMTI ratings.
