ACPL-268KL-300

Overview

The ACPL-268KL-300 is a high-speed optocoupler manufactured by Broadcom Limited, housed in a hermetically sealed 16-DIP package. It features two independent channels with a data rate of 10 Mb/s and an isolation voltage of 1500 Vdc. The device utilizes Photo IC output types with Schottky clamping for open collector logic outputs. 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. Operating temperatures range from -55 C to +100 C.

Feature Summary

• Hermetically sealed construction ensures reliability in harsh environments
• High common mode transient immunity supports noise-sensitive applications
• Schottky clamped outputs provide fast switching performance

Applications

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

Procurement Notes

Verify the specific ordering suffix KL-300 against the manufacturer datasheet to confirm package type and sealing characteristics. Ensure compatibility with existing DIP-16 footprints. Check RoHS status as indicated in official documentation. Confirm availability through authorized distributors due to potential supply chain variations.

Selection Notes

Select this component when high-speed digital isolation is required alongside robust environmental protection. The hermetic seal distinguishes it from standard plastic packages. Verify that the 10 Mb/s data rate meets system timing requirements. Consider the open collector output configuration for interfacing with compatible logic families.

Part Context

This part belongs to the ACPL-2 series of high-speed optocouplers. It is designed for applications requiring galvanic isolation between circuits. The Class K designation typically refers to specific hermetic packaging standards within the Broadcom portfolio. It serves as a critical interface component in systems demanding high reliability and signal integrity.

Replacement Considerations

Consult the official replacement guide for direct substitutes. Generic equivalents may lack hermetic sealing or identical CMTI ratings. Verify pinout compatibility before substitution.
