• Power electronics control circuits

Digital Isolators Procurement Notes

Verify the specific suffix against official Skyworks documentation to confirm pinout and electrical characteristics. Ensure the integrated DC-DC converter requirements match your system design. Confirm availability status as distribution listings may vary. Cross-reference the datasheet for thermal management needs in the SOIC-Wide-20 package.

Digital Isolators Selection Notes

Select this component when a compact solution combining signal isolation and isolated power delivery is required. The integrated DC-DC converter simplifies board layout by eliminating external isolated power supplies. Consider the 100 Mb/s data rate and 5000 Vrms isolation rating for high-noise environments.

Digital Isolators Part Context

This part belongs to the Si88322 series of digital isolators from Skyworks Solutions. The series is designed for applications demanding high reliability and compact form factors. The BD suffix typically indicates a wide-body SOIC package suitable for higher creepage distances.

Digital Isolators Replacement Considerations

SI88322BD-AS is a similar variant without the integrated DC-DC converter. Verify if the external power supply requirement is acceptable before substituting.
