SN74LV4066APWR from Texas Instruments, in a TSSOP-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1A | bidirectional | Input/Output to switch channel 1 |
| 2 | 1B | bidirectional | Input/Output to switch channel 1 |
| 3 | 2B | bidirectional | Input/Output to switch channel 2 |
| 4 | 2A | bidirectional | Input/Output to switch channel 2 |
| 5 | 2C | input | Control line for channel 2; switch is ON when control pin is high |
| 6 | 3C | input | Control line for channel 3; switch is ON when control pin is high |
| 7 | GND | power_in | Ground (0V) reference |
| 8 | 3A | bidirectional | Input/Output to switch channel 3 |
| 9 | 3B | bidirectional | Input/Output to switch channel 3 |
| 10 | 4B | bidirectional | Input/Output to switch channel 4 |
| 11 | 4A | bidirectional | Input/Output to switch channel 4 |
| 12 | 4C | input | Control line for channel 4; switch is ON when control pin is high |
| 13 | 1C | input | Control line for channel 1; switch is ON when control pin is high |
| 14 | VCC | power_out | Positive power supply; connect a decoupling capacitor ranging from 0.1µF to 10µF between VCC and GND for reliable operation |
