ACSL-6420-00TE

Overview

The ACSL-6420-00TE is a high-speed logic output optoisolator manufactured by Broadcom Limited. It features four independent channels within a single 16-SOIC package, supporting data rates up to 15 MBd. The device provides an isolation voltage of 2500 Vrms and exhibits a common-mode transient immunity of 10 kV/µs. Electrical specifications include a typical forward voltage of 1.52 V, a maximum DC forward current of 15 mA, and an output current capability of 50 mA per channel. The unit operates on supply voltages ranging from 3.0 V to 5.5 V and functions reliably across a temperature range of -40°C to +100°C.

Feature Summary

• Integrates four isolated channels in a compact surface-mount package for space-constrained designs.
• Delivers high-speed signal transmission with a 15 MBd data rate capability.
• Provides robust noise immunity through a 10 kV/µs common-mode transient rejection rating.
• Features open-collector outputs with Schottky clamping to minimize storage time and improve switching speed.

Applications

• High-speed digital communication interfaces requiring galvanic isolation.
• Industrial control systems utilizing noisy power environments.
• Data acquisition systems needing precise signal transfer between ground domains.
• Power supply feedback loops for monitoring and regulation.

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to ensure correct packaging configuration. Confirm that the selected variant matches the required lead times and production status. Cross-reference the datasheet revision history to validate compliance with current RoHS standards and marking requirements before finalizing procurement orders.

Selection Notes

Select this component when multiple isolated channels are required within a single footprint to reduce board area. Ensure the system design accommodates the 15 MBd propagation delay limits and the 2500 Vrms isolation barrier. Verify that the input current does not exceed the 15 mA maximum rating while maintaining sufficient drive for the 50 mA output sink capability under load conditions.

Part Context

This device belongs to the ACSL series of high-speed optocouplers designed for demanding digital isolation applications. It complements other variants in the family by offering a quad-channel configuration suitable for parallel data buses or multi-signal isolation tasks where size and speed are critical constraints.

Replacement Considerations

Direct replacements include the ACSL-6400-00TE and ACSL-6420-50TE. Verify pinout compatibility and packaging differences, as some variants may utilize tape-and-reel packaging instead of tubes. Ensure electrical parameters such as CMTI and propagation delay remain consistent with the original design requirements.
