Logic Output Optoisolators Procurement Notes

Verify the specific suffix 'K' indicates the hermetically sealed ceramic package variant distinct from plastic packages. Confirm RoHS status as non-compliant due to lead content in the ceramic seal. Ensure compatibility with existing PCB footprints for 8-pin DIP configurations during integration planning.

Logic Output Optoisolators Selection Notes

Select this component when high reliability and hermetic sealing are required for harsh environments. The Class K rating ensures superior performance compared to standard plastic optocouplers. Consider the wider operating temperature range and higher isolation voltage for critical safety applications.
