CD74HCT4067M from Texas Instruments, in a SOIC-24-300mil. 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 | COMMON | bidirectional | Common analog input/output terminal that connects to the selected channel via the internal multiplexer. |
| 2 | I7 | bidirectional | Analog channel input/output terminal; bidirectional analog line that switches to or from the common terminal. |
| 3 | I6 | bidirectional | Analog channel input/output terminal; bidirectional analog line that switches to or from the common terminal. |
| 4 | I5 | bidirectional | Analog channel input/output terminal; bidirectional analog line that switches to or from the common terminal. |
| 5 | I4 | bidirectional | Analog channel input/output terminal; bidirectional analog line that switches to or from the common terminal. |
| 6 | I3 | bidirectional | Analog channel input/output terminal; bidirectional analog line that switches to or from the common terminal. |
| 7 | I2 | bidirectional | Analog channel input/output terminal; bidirectional analog line that switches to or from the common terminal. |
| 8 | I1 | bidirectional | Analog channel input/output terminal; bidirectional analog line that switches to or from the common terminal. |
| 9 | I0 | bidirectional | Analog channel input/output terminal; bidirectional analog line that switches to or from the common terminal. |
| 10 | S0 | input | Binary select input; bit 0 of the 4-bit address code to select one of 16 analog channels. |
| 11 | S1 | input | Binary select input; bit 1 of the 4-bit address code to select one of 16 analog channels. |
| 12 | GND | power_in | Ground pin; negative power supply return. |
