Digital Isolators Procurement Notes

Verify the specific suffix 'AUR' confirms the reel packaging format and the inclusion of shutdown functionality, as these attributes distinguish this variant from tube-packaged or non-shutdown versions within the Si865x family. Confirm that the QSOP-16 package matches your PCB footprint requirements and that the 2500 Vrms isolation rating meets your system safety standards.

Digital Isolators Selection Notes

Select this part when a five-channel configuration with mixed forward and reverse directions is required for automotive applications. It is suitable for designs needing integrated shutdown control and high common-mode transient immunity. Consider the 150 Mb/s data rate and low power consumption relative to other isolators in the series.

Digital Isolators Part Context

This component belongs to the Si865x series of digital isolators from Skyworks Solutions. The series offers various channel counts and isolation voltages. The SI8651BB-AUR specifically provides a five-channel solution with automotive certification, distinguishing it from non-automotive variants like the SI8651BB-AU which lacks the AEC-Q100 qualification.
