ACPL-2670L-100

Overview

The ACPL-2670L-100 is a commercial-grade, two-channel high-speed optocoupler housed in a 16-pin ceramic DIP package. It features hermetic sealing and gold-plated leads for robust performance. The device supports a data rate of 10 Mb/s with an isolation voltage of 1500 Vdc. Key electrical parameters include a current transfer ratio of 100%, a forward current of 20 mA, and a forward voltage of 1.5 V. Rise and fall times are specified at 90 ns and 40 ns respectively, with a power dissipation of 200 mW.

Feature Summary

• Hermetically sealed construction in a 16-pin ceramic DIP package ensures long-term reliability.
• High common-mode transient immunity of 1 kV/µs protects against noise interference.
• Schottky clamped output design enables fast switching speeds up to 10 Mb/s.
• Open collector output configuration provides flexibility for various logic interfacing.

Applications

• Industrial automation control systems
• Power supply feedback loops
• Signal isolation in noisy environments

Procurement Notes

Verify the specific suffix '100' corresponds to the required lead form or packaging option, as variations exist within the ACPL-2670L family. Confirm that the 16-pin ceramic DIP package aligns with your PCB footprint requirements. Ensure the 1500 Vdc isolation rating meets your safety standards. Check for RoHS compliance documentation if required by your manufacturing process. Validate that the 20 mA forward current capability suits your drive circuit design.

Selection Notes

Select this component when high-speed digital isolation is required in harsh industrial environments. The hermetic seal makes it suitable for applications where moisture resistance is critical. Compare rise and fall times against system timing constraints to ensure signal integrity. Consider the open-collector output type for level shifting needs. Evaluate the thermal management requirements given the 200 mW power dissipation limit.

Part Context

This part belongs to Broadcom's ACPL series of high-speed optocouplers. It shares architectural similarities with other models like the ACPL-5601L but differs in channel count and package style. The ACPL-2670L specifically targets applications requiring dual-channel isolation with high reliability. Its ceramic DIP package distinguishes it from plastic-packaged alternatives in the same speed class.

Replacement Considerations

Direct substitutes may include other 16-pin ceramic DIP optocouplers with similar 10 Mb/s speed ratings. Verify pinout compatibility before swapping. Alternative brands offering hermetically sealed high-speed isolators should be evaluated for matching isolation voltages and current transfer ratios.
