Logic Output Optoisolators Procurement Notes

Verify the specific suffix #100 against official Broadcom documentation to confirm package type and lead finish specifications. Ensure that procurement sources provide valid manufacturer traceability and quality certifications required for Class H applications. Confirm compliance with relevant space or military standards if applicable to the end-use system requirements.

Logic Output Optoisolators Selection Notes

Select this component when hermetic sealing and high thermal stability are critical for long-term reliability. The open-collector output requires appropriate external pull-up resistors for logic interfacing. Consider the 10 MBd data rate limit and 1500 VDC isolation rating to ensure compatibility with system voltage and speed requirements.

Logic Output Optoisolators Part Context

This part belongs to the HCPL series of high-speed optocouplers from Broadcom Limited. It is distinguished by its hermetically sealed ceramic DIP package and gold-plated leads, which differentiate it from standard plastic-packaged variants. The series is engineered for applications requiring superior environmental resistance and signal integrity over extended operational lifetimes.
