**Skyworks Solutions** · Digital Isolators · SOIC-8

SI8715BC-A-IS 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 | NC | unconnected | No connect; the pin is not internally connected and should be tied to the ground plane to maximize CMTI performance. |
| 2 | ANODE | input | Anode of the LED emulator; VO follows the signal applied to this input with respect to the CATHODE input. |
| 3 | CATHODE | input | Cathode of the LED emulator; VO follows the signal applied to ANODE with respect to this input. |
| 4 | NC | unconnected | No connect; the pin is not internally connected and should be tied to the ground plane to maximize CMTI performance. |
| 5 | GND | power_in | Ground reference for VDD; typically connected to ground but may be tied to a negative or positive voltage. |
| 6 | VO | output | Output signal. |
| 7 | NC | unconnected | No connect; the pin is not internally connected and should be tied to the ground plane to maximize CMTI performance. |
| 8 | VDD | power_in | Output-side power supply input referenced to GND, 5.5 V max. |
