ACSL-6400-56T

Overview

The Broadcom ACSL-6400-56T is a high-speed digital optocoupler featuring four independent channels in a 16-SOIC package. It supports data rates up to 15 MBd with propagation delays of 100 ns maximum. The device provides 2500 Vrms isolation voltage and a common-mode transient immunity of 10 kV/µs. Operating on a supply voltage range of 3.0 V to 5.5 V, it utilizes open collector outputs with Schottky clamping. Typical rise and fall times are 30 ns and 12 ns respectively, ensuring rapid signal transitions for demanding industrial applications.

Feature Summary

• Four-channel architecture for multi-signal isolation
• High common-mode transient immunity for noise rejection
• Schottky-clamped open-collector output structure
• Wide operating temperature range capability

Applications

• Industrial networking systems
• Power management circuit isolation
• Communication interface isolation

Procurement Notes

Verify the specific suffix '56T' against current manufacturer documentation, as availability may vary. Confirm RoHS compliance status and lead time requirements directly with authorized distributors. Ensure the ordering part number matches the exact package and termination specifications required for your PCB layout. Cross-reference datasheet revisions to confirm pinout consistency before finalizing procurement orders.

Selection Notes

Select this component when four isolated channels are required within a single compact surface-mount footprint. The 15 MBd speed rating suits high-frequency digital communication links. Verify that the 2500 Vrms isolation level meets safety standards for your specific application voltage levels. Consider the open-collector output configuration for compatibility with downstream logic families requiring pull-up resistors.

Part Context

The ACSL-6400 series represents Broadcom's high-performance family of quad-channel optocouplers designed for robust signal transmission across isolated boundaries. This model specifically targets applications needing fast switching speeds and high noise immunity. The 16-SOIC package facilitates automated assembly and space-constrained board designs compared to wider DIP alternatives.

Replacement Considerations

Check for direct substitutes like the ACSL-6400-56TE if tape-and-reel packaging is preferred over tubes. Verify functional equivalence with other quad-channel high-speed optocouplers from different manufacturers by comparing isolation ratings and propagation delay specifications.
