SOIC-8 (Small Outline IC 8-pin) is the SMD equivalent of DIP-8, used for op-amps, voltage regulators, EEPROMs, and MOSFETs in surface mount applications. Pin 1 is marked by a dot or chamfer on the package.
| Pin | Name | Function | Type |
|---|---|---|---|
| 1 | Pin 1 | Function varies by IC (dot marks pin 1) | I/O |
| 2 | Pin 2 | Function varies by IC | I/O |
| 3 | Pin 3 | Function varies by IC | I/O |
| 4 | GND | Ground (most SOIC-8 ICs) | GND |
| 5 | Pin 5 | Function varies by IC | I/O |
| 6 | Pin 6 | Function varies by IC | I/O |
| 7 | Pin 7 | Function varies by IC | I/O |
| 8 | VCC | Positive supply (most SOIC-8 ICs) | PWR |
