ACSL-6420-50TE

Overview

The Broadcom ACSL-6420-50TE is a high-speed 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 operates on a supply voltage range of 3.0V to 5.5V and provides 2500 Vrms isolation. Output stages utilize open collector configurations with Schottky clamping, delivering a maximum output current of 50 mA per channel. It exhibits a common-mode transient immunity of 10 kV/µs and functions within an operating temperature range of -40°C to +100°C.

Feature Summary

• Four-channel architecture for multi-signal isolation
• Schottky-clamped open-collector outputs for fast switching
• High common-mode transient immunity for noise rejection
• Wide operating temperature range for industrial environments

Applications

• Industrial automation control systems
• Communication interface isolation
• Power supply feedback loops
• Signal transmission across ground potential differences

Procurement Notes

Verify the specific suffix '50TE' confirms the tape-and-reel packaging format, as other suffixes may indicate tube packaging. Ensure the procurement order matches the required RoHS compliance status and moisture sensitivity level. Confirm that the 16-SOIC footprint aligns with the target PCB design constraints before finalizing the purchase order.

Selection Notes

Select this component when four isolated channels are required within a single package to save board space. The 15 MBd data rate suits moderate-speed digital communication interfaces. Consider the open-collector output type, which requires external pull-up resistors, unlike push-pull alternatives. Verify that the 2500 Vrms isolation rating meets the safety requirements of the application circuit.

Part Context

This part belongs to the Broadcom ACSL series of high-speed optocouplers. The series is designed for applications requiring reliable signal transmission between isolated circuits. The ACSL-6420 variant specifically integrates four channels, distinguishing it from single or dual-channel counterparts in the same family.

Replacement Considerations

ACSL-6420-00TE serves as a functional substitute with identical electrical characteristics but differs in packaging configuration.
