Logic Output Optoisolators Procurement Notes

Verify the specific manufacturer source, as historical documentation may reference Hewlett Packard or Avago. Confirm that the ceramic LCCC-20 package matches your PCB footprint requirements. Ensure compliance with RoHS status if applicable, as older manufacturing runs may differ. Validate the hermetic seal integrity for space or military-grade qualification needs before final procurement.

Logic Output Optoisolators Selection Notes

Select this component when high-speed isolation exceeding standard optocoupler limits is required. The dual-channel configuration reduces board space compared to single-channel alternatives. Consider the ceramic package for harsh environments where plastic packages might fail. Ensure the 1500 Vrms isolation rating meets system safety standards. Verify that the 5 MB/s data rate aligns with the target communication protocol speed.
