Logic Output Optoisolators Procurement Notes

Verify the specific suffix '500E' to confirm the surface-mount 8-DIP gull-wing packaging variant, as other suffixes may indicate through-hole configurations. Ensure compliance with RoHS directives if required by your assembly process, noting that some sources indicate non-compliance for certain revisions. Confirm the operating temperature range meets your environmental specifications before finalizing procurement orders.

Logic Output Optoisolators Selection Notes

Select this component when a 10 MBd data rate and open collector logic output are required for isolated applications. The surface-mount package facilitates automated PCB assembly compared to through-hole alternatives. Consider the 10 kV/µs CMTI rating for environments with significant electrical noise. Verify that the 50 mA output sink current capacity aligns with the load requirements of the receiving circuitry.
