Logic Output Optoisolators Procurement Notes

Verify the specific suffix designation to confirm the exact packaging configuration, as variations exist between tape-and-reel and tube formats. Confirm RoHS compliance status through official documentation, as some variants may differ. Check component availability status carefully, as this series includes both active and obsolete part numbers. Ensure the selected variant matches the required mounting style for PCB layout compatibility.

Logic Output Optoisolators Selection Notes

Select this component when high-speed digital isolation is required between circuit sections. The Schottky-clamped output structure makes it suitable for applications demanding rapid signal transitions. Consider the 5000 V isolation rating for safety-critical interfaces. Evaluate the 8-SMD package dimensions against available board space constraints before finalizing the design.
