HCPL-540K-100

Logic Output Optoisolators Overview

The HCPL-540K-100 is a high-speed logic output optoisolator manufactured by Broadcom Limited. It features a single channel with tri-state logic output and supports data rates up to 40 Mbps. The device provides an isolation voltage of 1500 VDC and a common mode transient immunity (CMTI) of 500 V/µs. It operates within a supply voltage range of 4.75V to 5.25V. The component is housed in an 8-SMD butt joint package, designed for robust performance in demanding environments.

Logic Output Optoisolators Feature Summary

• Hermetically sealed construction ensuring high reliability and environmental protection
• Tri-state logic output capability for efficient bus interfacing
• High common mode transient immunity for noise resistance

Logic Output Optoisolators Applications

• Military and aerospace systems requiring Class K reliability
• High-speed digital signal isolation in industrial control
• Isolated communication interfaces in harsh environments

Logic Output Optoisolators Procurement Notes

Verify the specific suffix '100' indicates the 8-SMD butt joint package variant. Confirm that the unit meets MIL-PRF-38534 Class K or QML-38534 standards if military grade certification is required. Check RoHS compliance status as indicated in official documentation before procurement.

Logic Output Optoisolators Selection Notes

Select this component when hermetic sealing and high CMTI are critical for system integrity. Ensure the 8-SMD butt joint package fits the PCB layout constraints. Verify that the 40 Mbps data rate and 1500 VDC isolation meet the specific application requirements compared to standard plastic-packaged alternatives.

Logic Output Optoisolators Part Context

This part belongs to the HCPL-540K series of high-speed optocouplers from Broadcom. The series is known for its ceramic DIP packaging and adherence to strict military reliability standards. It serves as a specialized solution for applications where standard commercial-grade optocouplers fail due to environmental stress or speed limitations.

Logic Output Optoisolators Replacement Considerations

Direct replacements must match the hermetic seal, tri-state output, and 8-SMD butt joint package. Generic non-hermetic optocouplers may not suffice for Class K applications. Verify pinout compatibility and electrical parameters such as CMTI and isolation voltage before substitution.
