Digital Isolators Procurement Notes

Verify the specific suffix 'BA' indicates the narrow SOIC-16 package variant distinct from wide packages. Confirm AEC-Q100 qualification status aligns with target application requirements. Ensure input voltage levels match the specified 2.375 V to 5.5 V operational range. Check for moisture sensitivity labeling on packaging to determine bake-out procedures if necessary.

Digital Isolators Selection Notes

Select this component when five independent unidirectional channels are required within a single package. Consider the 1000 Vrms insulation rating for basic isolation needs rather than reinforced isolation applications. Evaluate the 150 Mb/s data rate against system timing constraints. Compare power consumption characteristics against other channel counts if fewer or more channels are needed.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators designed for high-reliability applications. It complements other variants in the series that offer different channel counts or insulation voltages. The family utilizes Skyworks' proprietary capacitive isolation technology to provide robust performance without optical components.
