SI8423BB-D-ISR from Skyworks Solutions, 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 | VDD1 | power_in | Side 1 power supply; the datasheet requires a 0.1 μF bypass capacitor between VDD1 and GND1 placed as close to the package as possible. |
| 2 | A1 | input | Side 1 digital input or output; for the Si8423 this channel is an input per the ordering guide. |
| 3 | A2 | input | Side 1 digital input or output; for the Si8423 this channel is an input per the ordering guide. |
| 4 | GND1 | power_in | Side 1 ground. |
| 5 | GND2 | power_in | Side 2 ground. |
| 6 | B2 | output | Side 2 digital input or output; for the Si8423 this channel is an output per the ordering guide. |
| 7 | B1 | output | Side 2 digital input or output; for the Si8423 this channel is an output per the ordering guide. |
| 8 | VDD2 | power_in | Side 2 power supply; the datasheet requires a 0.1 μF bypass capacitor between VDD2 and GND2 placed as close to the package as possible. |
