Procurement Notes

Verify the specific ordering suffix matches the required packaging format, such as tape and reel configurations. Confirm that the component meets the necessary safety certifications for the target application region. Ensure the supply chain source is authorized to guarantee genuine Panasonic products. Check for any specific handling requirements related to moisture sensitivity levels indicated in the datasheet.

Selection Notes

Select this component when high-speed data transfer is critical alongside strong isolation requirements. The push-pull output is suitable for driving logic inputs directly without additional buffering. Consider the 20 Mbps limit when designing for higher bandwidth applications. Evaluate the thermal performance given the power dissipation constraints under continuous operation conditions.
