ACFL-6211U-000E

Overview

The ACFL-6211U-000E is a dual-channel high-speed optocoupler manufactured by Broadcom Limited. It features push-pull totem pole outputs and provides 5000 Vrms isolation voltage with a common mode transient immunity of 15 kV/µs. The device supports data rates up to 15 Mb/s, operates within an extended temperature range of -40°C to +125°C, and utilizes an SO-12 package. Key electrical parameters include a forward current of 20 mA, forward voltage of 1.5 V, rise and fall times of 10 ns, and an output current capability of 10 mA.

Feature Summary

• Dual-channel bidirectional digital communication capability
• Push-pull totem pole logic outputs for robust signal transmission
• Extended industrial operating temperature range
• High common mode transient immunity for noise rejection

Applications

• Industrial automation systems requiring isolated digital interfaces
• Bi-directional data communication in noisy environments
• Power supply control circuits with galvanic isolation requirements
• Microcontroller interface applications needing high-speed signal transfer

Procurement Notes

Verify the specific suffix (e.g., 000E vs 060E) against your bill of materials, as packaging and regional availability may vary. Confirm that the SO-12 package footprint matches your PCB design. Check current lifecycle status, as some variants may be discontinued or subject to limited supply constraints. Ensure compliance with RoHS directives if required for your target market.

Selection Notes

Select this component when bidirectional high-speed data transfer is required across an isolation barrier. The push-pull output stage eliminates the need for external pull-up resistors, simplifying circuit design. Consider the 15 kV/µs CMTI rating for applications with significant switching noise. Verify that the 5000 Vrms isolation rating meets safety standards for your specific application environment.

Part Context

This part belongs to the Broadcom ACPL/ACFL series of extended temperature optocouplers. These devices are designed for reinforced insulation and reliability in safety-critical applications. The ACFL-6211U variant specifically targets bi-directional communication needs, distinguishing it from unidirectional counterparts in the same family.

Replacement Considerations

Direct replacements must match the dual-channel configuration, SO-12 package, and 15 Mb/s speed. Verify equivalent isolation voltage and CMTI ratings. Cross-reference pinouts carefully, as internal channel mapping may differ between manufacturers. Consult official substitution guides for confirmed compatible parts.
