ACSL-6400-50TE

Overview

The Broadcom ACSL-6400-50TE is a high-speed, four-channel optocoupler housed in a 16-SOIC surface-mount package. It operates within a supply voltage range of 3.0V to 5.5V and supports data rates up to 15 MBd. The device features open-collector outputs with Schottky clamping and provides an isolation voltage of 2500 Vrms. Key electrical parameters include a maximum forward current of 15 mA, typical forward voltage of 1.52 V, and output current per channel of 50 mA. Propagation delays are limited to 100 ns, with rise and fall times of 30 ns and 12 ns respectively. It offers a common-mode transient immunity of 10 kV/µs and functions across temperatures from -40°C to 100°C.

Feature Summary

• Integrates four independent channels in a monolithic structure for multi-channel signal isolation.
• Features open-collector outputs with integrated Schottky clamping for enhanced switching performance.
• Provides high common-mode transient immunity to maintain signal integrity in noisy environments.

Applications

• Industrial networking systems requiring isolated digital communication
• Data acquisition systems with diverse voltage levels
• General-purpose logic isolation in electronic circuits

Procurement Notes

Verify the specific suffix '50TE' against official datasheets to confirm packaging and material compliance. Ensure the selected variant matches the required tape-and-reel or cut-tape configuration. Cross-reference RoHS status and moisture sensitivity levels with current manufacturing notices before procurement.

Selection Notes

Select this component when four isolated channels are required in a single package. The 15 MBd speed suits moderate-speed digital interfaces. Verify that the 50 mA output current meets load requirements. The 2500 Vrms isolation rating defines the safety barrier limits for the application design.

Part Context

This part belongs to the ACSL-64xx family of high-speed optocouplers. Variants like ACSL-6410 and ACSL-6420 share similar electrical characteristics but differ in pin configurations or internal channel arrangements. The ACSL-6400 specifically utilizes a 4-input, 0-output side configuration for unidirectional logic isolation.

Replacement Considerations

Check for direct substitutes within the ACSL-64xx series such as ACSL-6410-50TE or ACSL-6420-50TE. Confirm pinout compatibility and identical isolation ratings before substitution. Verify that alternative packages match the 16-SOIC footprint.
