Logic Output Optoisolators Procurement Notes

Verify the specific suffix #020 confirms the 5000 Vrms insulation rating, as other variants may offer lower ratings. Confirm the DIP-8 through-hole package type matches your PCB footprint requirements. Ensure the operating temperature range meets your system's thermal specifications. Check RoHS compliance status if required by your manufacturing standards. Validate that the 1 MBd data rate is sufficient for your application's signal frequency.

Logic Output Optoisolators Selection Notes

Select this component when high isolation voltage and fast switching are critical for power electronics. The integrated pull-up resistor makes it suitable for direct IPM interfacing without additional components. Consider the 15 mA continuous output current limit for load driving capabilities. Evaluate the 650 ns maximum propagation delay against your timing constraints. Ensure the 4.5V to 30V supply voltage range aligns with your control circuit design.
