Digital Isolators Procurement Notes

Verify the specific suffix 'AUR' corresponds to the reel packaging configuration as indicated by distributor listings. Confirm that the component meets the required AEC-Q100 automotive qualification standards for your specific application environment. Ensure the 16-lead QSOP footprint matches your PCB layout constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when four-channel unidirectional isolation is required for automotive applications. Consider the 150 Mb/s data rate limit and 2500 Vrms isolation rating against system requirements. Evaluate the 16-lead QSOP package dimensions for space constraints. Verify compatibility with the specified 2.375 V to 5.5 V supply voltage range for the target logic levels.

Digital Isolators Part Context
