SN74AHC4066PWR from Texas Instruments, in a TSSOP-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 input/output; switch I/O voltage must stay within -0.5 V to VCC + 0.5 V (absolute maximum). |
| 2 | 1B | bidirectional | Switch 1 output/input; switch I/O voltage must stay within -0.5 V to VCC + 0.5 V (absolute maximum). |
| 3 | 2B | bidirectional | Switch 2 output/input; switch I/O voltage must stay within -0.5 V to VCC + 0.5 V (absolute maximum). |
| 4 | 2A | bidirectional | Switch 2 input/output; switch I/O voltage must stay within -0.5 V to VCC + 0.5 V (absolute maximum). |
| 5 | 2C | input | Switch 2 control; a high level turns the switch on, with control input voltage range 0 V to 5.5 V. |
| 6 | 3C | input | Switch 3 control; a high level turns the switch on, with control input voltage range 0 V to 5.5 V. |
| 7 | GND | power_in | Ground reference; all voltages are referenced to ground. |
| 8 | 3A | bidirectional | Switch 3 input/output; switch I/O voltage must stay within -0.5 V to VCC + 0.5 V (absolute maximum). |
| 9 | 3B | bidirectional | Switch 3 output/input; switch I/O voltage must stay within -0.5 V to VCC + 0.5 V (absolute maximum). |
| 10 | 4B | bidirectional | Switch 4 output/input; switch I/O voltage must stay within -0.5 V to VCC + 0.5 V (absolute maximum). |
| 11 | 4A | bidirectional | Switch 4 input/output; switch I/O voltage must stay within -0.5 V to VCC + 0.5 V (absolute maximum). |
| 12 | 4C | input | Switch 4 control; a high level turns the switch on, with control input voltage range 0 V to 5.5 V. |
| 13 | 1C | input | Switch 1 control; a high level turns the switch on, with control input voltage range 0 V to 5.5 V. |
| 14 | VCC | power_in | Supply voltage, 1 V to 5.5 V recommended operation; absolute maximum is 7 V. |
