Digital Isolators Procurement Notes

Verify the specific suffix 'AU' indicates the standard tape-and-reel packaging configuration as defined by Skyworks. Confirm that the ordering part number matches the exact pinout and isolation ratings required for your design. Cross-reference the datasheet revision date to ensure compatibility with current manufacturing standards. Ensure compliance with RoHS directives if applicable to your region.

Digital Isolators Selection Notes

Select this component when dual-channel isolation is required with moderate speed requirements up to 150 Mbps. Consider the 5000 Vrms isolation rating for safety compliance. Evaluate the 7 ns propagation delay against system timing constraints. Compare power consumption metrics against other isolators if energy efficiency is a primary design driver.

Digital Isolators Part Context

This model belongs to the Skyworks Si86xx family of digital isolators. These devices replace traditional optocouplers in many applications due to superior performance consistency and lower power consumption. The family offers various channel configurations and isolation voltages to suit diverse industrial and commercial needs.

Digital Isolators Replacement Considerations

Direct replacements include other Skyworks Si865x series variants with matching channel counts. Verify pin-to-pin compatibility with competitors like Analog Devices ADuM series or Texas Instruments ISO77xx series before substitution. Ensure isolation voltage and CMTI specifications meet or exceed original design requirements.
