Logic Output Optoisolators Procurement Notes

Verify the specific suffix '#300' against the manufacturer's official documentation to confirm packaging and compliance status. Note that some sources indicate this variant may not be RoHS compliant. Ensure the ordering part number matches the exact datasheet revision required for your design. Cross-reference the 8-DIP gull-wing package dimensions with your PCB footprint library before procurement to avoid assembly errors.

Logic Output Optoisolators Selection Notes

Select this component when a single-channel, high-speed logic interface is required with robust noise immunity. The wide operating voltage range of 4.5 V to 20 V allows flexibility in power supply design. Consider the 5000 Vrms isolation rating for safety-critical applications. Compare performance metrics such as propagation delay and CMTI against alternative optocouplers if stricter timing or noise constraints exist in the target application.
