SI8602AC-B-ISR

SILICON LABS · Digital Isolators · SOIC-8

SI8602AC-B-ISR from SILICON LABS, in a SOIC-8. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 AVDD power_in Side A power supply terminal; connect to a source of 3.0 to 5.5 V.
2 ASDA bidirectional Side A data (open drain) input or output.
3 ASCL input Side A clock input; for the Si8602 it is a standard CMOS input rather than open drain.
4 AGND power_in Side A ground terminal.
5 BGND power_in Side B ground terminal.
6 BSCL output Side B clock output; push-pull output for the Si8602.
7 BSDA bidirectional Side B data (open drain) input or output.
8 BVDD power_in Side B power supply terminal; connect to a source of 3.0 to 5.5 V.
