ACSL-6400-56TE

Overview

The Broadcom ACSL-6400-56TE is a high-speed logic output optocoupler featuring four independent channels in a 16-SOIC package. It supports data rates up to 15 MBd with a minimum common-mode transient immunity of 10 kV/µs. The device operates within a supply voltage range of 3.0 V to 5.5 V and provides an isolation voltage of 2500 Vrms. Key electrical parameters include a maximum forward current of 15 mA, typical propagation delays of 100 ns, and rise/fall times of 30 ns and 12 ns respectively. It functions as an open collector output with Schottky clamping.

Feature Summary

• High-speed digital isolation with 15 MBd data rate capability
• Robust noise immunity via 10 kV/µs common-mode transient rejection
• Integrated Schottky clamping on open collector outputs for enhanced switching performance

Applications

• Full duplex communication systems
• Isolated line receivers
• Microprocessor system interfaces
• Digital isolation for A/D and D/A converters

Procurement Notes

Verify the specific ordering suffix '-56TE' against official Broadcom documentation to confirm packaging configuration and marking details. Ensure compatibility with RoHS3 standards and check for any recent Product Change Notifications (PCN) regarding assembly or labeling revisions that may affect integration into existing designs.

Selection Notes

Select this component when high-speed signal transmission across isolated boundaries is required alongside strong noise immunity. The 15 MBd rate suits serial peripheral interfaces like SPI and I2C. The 16-SOIC form factor facilitates surface-mount assembly, while the wide operating temperature range supports industrial environments.

Part Context

This part belongs to the ACSL-64xx series of high-speed optocouplers from Broadcom Limited. The series is designed for applications demanding fast response times and reliable galvanic isolation between low-voltage control circuits and higher-voltage power stages or noisy environments.

Replacement Considerations

Direct substitutes within the same family include ACSL-6400-00TE and ACSL-6400-50TE. Verify pinout compatibility and ensure the alternative suffix matches the required tape-and-reel or cut-tape packaging specifications before substitution.
