HCPL-268K-100

Logic Output Optoisolators Overview

The HCPL-268K-100 is a high-speed, two-channel logic output optoisolator manufactured by Broadcom Limited. It features an open collector output configuration with Schottky clamping to minimize storage time. The device provides 1500VDC isolation voltage and operates within a data rate of 10 Mb/s. Key electrical parameters include a forward current of 20 mA, forward voltage of 1.5 V, reverse voltage of 5 V, and maximum output current of 25 mA. Power dissipation is rated at 200 mW. Timing characteristics specify a rise time of 90 ns and a fall time of 40 ns. The component supports an operating temperature range from -55°C to 125°C.

Logic Output Optoisolators Feature Summary

• Hermetically sealed Class K reliability in a ceramic package
• Schottky clamped outputs for fast switching performance
• High common mode transient immunity

Logic Output Optoisolators Applications

• Industrial process control systems
• Power supply feedback loops
• Solid-state relay driver circuits

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '100' indicates the surface mount butt joint variant rather than the standard through-hole DIP version. Confirm that the hermetic seal and gold-plated leads meet the required environmental standards for the target application. Ensure the open collector output type aligns with the downstream logic interface requirements.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required alongside extreme reliability standards. The Class K hermetic construction distinguishes it from standard plastic-packaged alternatives. Consider the 1500VDC isolation barrier and 10 Mb/s data rate for noise-immune communication links in electrically noisy environments.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-268 series of high-speed optocouplers. It shares functional similarities with other Broadcom logic output isolators but is distinguished by its hermetically sealed ceramic package and Class K reliability rating. The series is designed for applications demanding long-term stability and resistance to harsh conditions.
