Procurement Notes

Verify the specific suffix designation when ordering, as it determines the packaging format such as tape and reel or cut tape. Confirm RoHS3 compliance status if required by project specifications. Ensure the selected variant matches the required isolation voltage rating and channel configuration. Cross-reference the manufacturer part number with distributor catalogs to confirm availability and lead times prior to procurement planning.

Selection Notes

Select this component for applications demanding high-speed digital isolation with integrated power management. The 150Mbps rate suits fast communication protocols, while the 5000Vrms rating ensures safety in high-voltage environments. Consider the 16-SOIC footprint for PCB layout constraints. Evaluate the 100kV/µs CMTI against noise levels in the target application to ensure reliable operation without external filtering.
