Logic Output Optoisolators Procurement Notes

Verify the specific suffix '320' against official Broadcom documentation to confirm pinout and electrical characteristics match the design requirements. Ensure compliance with RoHS directives as indicated by the 'E' suffix if applicable. Cross-reference datasheet revisions to validate performance metrics such as CMTI and propagation delay before finalizing component selection.

Logic Output Optoisolators Selection Notes

Select this component when high-speed data transmission exceeding standard optocoupler capabilities is required. The Schottky-clamped output ensures fast switching suitable for logic-level signals. Consider the 5000 Vrms isolation rating for safety-critical applications. Verify that the 5 mA drive current aligns with the source circuit capabilities and that the DIP-8 package fits the PCB layout constraints.
