SN74AHC4066DR from Texas Instruments, 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 | 1A | bidirectional | Switch 1 bidirectional signal terminal for analog or digital signals up to 5.5V peak amplitude. |
| 2 | 1B | bidirectional | Switch 1 bidirectional signal terminal for analog or digital signals up to 5.5V peak amplitude. |
| 3 | 2B | bidirectional | Switch 2 bidirectional signal terminal for analog or digital signals up to 5.5V peak amplitude. |
| 4 | 2A | bidirectional | Switch 2 bidirectional signal terminal for analog or digital signals up to 5.5V peak amplitude. |
| 5 | 2C | input | Switch 2 control input; high logic level enables the switch, low level disables it. |
| 6 | 3C | input | Switch 3 control input; high logic level enables the switch, low level disables it. |
| 7 | GND | power_in | Ground, providing the 0V reference for all signal and power circuits. |
| 8 | 3A | bidirectional | Switch 3 bidirectional signal terminal for analog or digital signals up to 5.5V peak amplitude. |
| 9 | 3B | bidirectional | Switch 3 bidirectional signal terminal for analog or digital signals up to 5.5V peak amplitude. |
| 10 | 4B | bidirectional | Switch 4 bidirectional signal terminal for analog or digital signals up to 5.5V peak amplitude. |
| 11 | 4A | bidirectional | Switch 4 bidirectional signal terminal for analog or digital signals up to 5.5V peak amplitude. |
| 12 | 4C | input | Switch 4 control input; high logic level enables the switch, low level disables it. |
| 13 | 1C | input | Switch 1 control input; high logic level enables the switch, low level disables it. |
| 14 | VCC | power_in | Positive power supply, requires 1V to 5.5V operating range. |
