Digital Isolators Procurement Notes

Verify the specific suffix B-ISR confirms the SOIC-Wide-16 package and reel packaging format. Ensure the component meets AEC-Q100 grade specifications if deployed in automotive contexts. Cross-reference the datasheet for humidity sensitivity handling procedures during assembly. Confirm that the 1000 Vrms insulation rating aligns with system safety isolation requirements.

Digital Isolators Selection Notes

Select this component when five unidirectional channels are required with 1000 Vrms isolation. The 150 Mb/s data rate suits moderate-speed industrial protocols. Consider the SOIC-Wide-16 footprint for PCB layout compatibility. Verify thermal dissipation capabilities against the 415 mW power dissipation limit in enclosed designs.

Digital Isolators Part Context

This part belongs to the Si865x family of digital isolators, designed for robust signal transmission across isolation barriers. The series offers various channel counts and insulation ratings, with the SI8655 variant specifically providing five channels. The B-ISR suffix denotes the wide SOIC package and tape-and-reel delivery method.

Digital Isolators Replacement Considerations

SI8655BD-B-ISR: Offers higher 5000 Vrms insulation but shares similar pinout and performance characteristics.
