Digital Isolators Procurement Notes

Verify the specific suffix 'B' indicates the correct isolation rating and pin configuration for your design requirements. Confirm that the SOIC-Narrow-16 package dimensions match your PCB footprint constraints. Ensure compatibility with the required supply voltage range of 2.375 V to 5.5 V. Check for RoHS compliance status if environmental regulations apply to your manufacturing process.

Digital Isolators Selection Notes

Select this component when five independent unidirectional channels are required within a single package. Consider the 2500 Vrms insulation rating against system voltage requirements. Evaluate the 8 ns propagation delay against timing constraints of the communication protocol. Compare power dissipation characteristics against thermal management capabilities of the target application environment.

Digital Isolators Part Context

This part belongs to the Si865x family of general-purpose digital isolators. It shares functional similarities with other members like the SI8655BD-B-IS but differs in insulation voltage ratings and package types. The family is designed for applications requiring reliable signal transmission across isolation barriers without magnetic or optical components.
