ACPL-2672L

Overview

The ACPL-2672L is a high-speed optocoupler featuring two independent channels within a hermetically sealed DIP-16 package. It operates at a data rate of 10 Mb/s with a common mode transient immunity of 1 kV/µs and an isolation voltage of 1500 Vdc. The device utilizes photo IC outputs configured as open collector with Schottky clamping, supporting a forward current of 20 mA and a current transfer ratio of 100%. Key timing parameters include a rise time of 90 ns and a fall time of 40 ns, with a maximum power dissipation of 200 mW.

Feature Summary

• Hermetically sealed construction for enhanced environmental reliability
• High common mode transient immunity of 1 kV/µs
• Schottky-clamped open collector output configuration

Applications

• Industrial process control systems
• Power supply feedback loops
• Communication interface isolation

Procurement Notes

Verify the specific suffix (e.g., -100, -300) to ensure correct packaging and compliance status. Confirm RoHS designation as specifications may vary by production lot. Check lead times due to potential manufacturing delays. Ensure the DIP-16 through-hole footprint matches the target PCB design requirements before ordering.

Selection Notes

Select this component when hermetic sealing is required for harsh environments or high-reliability applications. The 10 Mb/s speed suits moderate-speed digital isolation needs. Verify that the 1500 Vdc isolation rating meets system safety standards. Consider the Schottky-clamped output characteristics for driving specific logic loads efficiently.

Part Context

This part belongs to the ACPL-2 series of high-speed optocouplers from Broadcom. It shares architectural similarities with models like the ACPL-2670L but differs in specific electrical ratings and packaging options. The hermetic seal distinguishes it from standard plastic-packaged variants, targeting aerospace, military, or critical industrial sectors.

Replacement Considerations

ACPL-2672L-100 and ACPL-2672L-300 are confirmed substitute part numbers within the same family. These variants share identical core electrical specifications but differ in trailing zeros indicating specific packaging or compliance configurations. Verify pinout compatibility before substitution.
