CAP1208-1-SL-TR from Microchip Tech, in a SOIC-14. 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 | CS2 | passive | Capacitive touch sensor input 2 (analog I/O); connect to ground when unused. |
| 2 | CS1 | passive | Capacitive touch sensor input 1 (analog I/O); connect to ground when unused. |
| 3 | ALERT# | output | Active low alert/interrupt output for SMBus alert; open drain, requires a pull-up resistor, and is 5V tolerant. |
| 4 | SMDATA | bidirectional | Bidirectional open-drain SMBus or I2C data line that requires a pull-up resistor; 5V tolerant. |
| 5 | SMCLK | input | SMBus or I2C clock input that requires a pull-up resistor; 5V tolerant. |
| 6 | N/C | unconnected | Not internally connected; connect to ground. |
| 7 | VDD | power_in | Positive power supply; operating range 3.0 V to 5.5 V with absolute maximum of -0.3 to 6.5 V. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | CS8 | passive | Capacitive touch sensor input 8 (analog I/O); connect to ground when unused. |
| 10 | CS7 | passive | Capacitive touch sensor input 7 (analog I/O); connect to ground when unused. |
| 11 | CS6 | passive | Capacitive touch sensor input 6 (analog I/O); connect to ground when unused. |
| 12 | CS5 | passive | Capacitive touch sensor input 5 (analog I/O); connect to ground when unused. |
| 13 | CS4 | passive | Capacitive touch sensor input 4 (analog I/O); connect to ground when unused. |
| 14 | CS3 | passive | Capacitive touch sensor input 3 (analog I/O); connect to ground when unused. |
