Procurement Notes

Verify the specific suffix designation against the manufacturer's official documentation to ensure the correct variant is procured. Confirm that the component meets RoHS3 compliance requirements for the intended market. Check the latest Product Change Notification (PCN) records for any updates regarding manufacturing site transfers or material changes. Ensure the ordering quantity aligns with the standard packaging specifications provided by the supplier.

Selection Notes

Select this component when dual-channel isolation is required alongside high-speed digital signaling up to 10 MBd. The open-drain output configuration necessitates external pull-up components; verify that the system voltage matches the 4.5V to 5.5V operating range. Consider the 4000Vrms isolation rating for applications involving significant ground potential differences. Evaluate the thermal performance within the specified -40°C to 100°C operating range for environmental suitability.
