Overview
The Broadcom ACSL-6420-56TE is a high-speed optocoupler featuring four independent channels in a 16-SOIC package. It supports data rates up to 15 Mb/s with an isolation voltage of 2500 Vrms. The device utilizes open collector outputs with Schottky clamping, operating within a supply voltage range of 3.0V to 5.5V. Key electrical parameters include a typical rise time of 35 ns and fall time of 12 ns, with a maximum forward current of 10 mA. It offers a common-mode transient immunity of 10 kV/µs and functions reliably across temperatures from -40°C to +100°C.
Feature Summary
- Four-channel configuration for multi-signal isolation
- High common-mode transient immunity for noise rejection
- Schottky-clamped open-collector outputs for fast switching
Applications
- Industrial communication bus isolation
- Signal isolation in noisy environments
- Logic interface between different voltage domains
Procurement Notes
Verify the specific suffix '56TE' against official datasheets to confirm packaging and material compliance details. Ensure compatibility with 16-SOIC footprint requirements during PCB layout. Confirm RoHS status and moisture sensitivity level prior to assembly planning.
Selection Notes
Select this component when four isolated channels are required at speeds up to 15 Mb/s. The open-collector output type necessitates external pull-up resistors. Verify that the 2500 Vrms isolation rating meets system safety standards and that the 10 kV/µs CMTI is sufficient for the application's noise environment.
Part Context
This part belongs to the Broadcom ACSL series of high-speed logic output optocouplers. The series is designed for applications requiring reliable signal transmission across isolation barriers with minimal propagation delay. The ACSL-6420 variant specifically provides a quad-channel solution in a compact surface-mount package.
Replacement Considerations
ACSL-6420-00TE and ACSL-6420-50TE are functionally similar quad-channel variants within the same family. Verify pinout and packaging consistency before substitution.
