MC74HC4051ADR2G from onsemi, in a SOIC-16. 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 | X4 | passive | Analog input/output channel 4 of the multiplexer, with the analog signal limited to the range VEE to VCC. |
| 2 | X6 | passive | Analog input/output channel 6 of the multiplexer, with the analog signal limited to the range VEE to VCC. |
| 3 | X | passive | Common analog output/input that is connected to the selected channel through the analog switch, and is disconnected when Enable is HIGH. |
| 4 | X7 | passive | Analog input/output channel 7 of the multiplexer, with the analog signal limited to the range VEE to VCC. |
| 5 | X5 | passive | Analog input/output channel 5 of the multiplexer, with the analog signal limited to the range VEE to VCC. |
| 6 | Enable | input | Active-HIGH disable input: when HIGH all analog switches are turned off, and it should be held at VCC or GND logic levels. |
| 7 | VEE | power_in | Negative supply, from −6.0 V up to GND (VEE ≤ GND), which sets the analog swing with VCC − VEE of 2.0 to 12.0 V. |
| 8 | GND | power_in | Digital ground reference (0 V) for the Channel-Select and Enable inputs, with VCC − GND of 2.0 to 6.0 V. |
| 9 | C | input | Channel-select input C, a binary address bit that must be held at VCC or GND logic levels. |
| 10 | B | input | Channel-select input B, a binary address bit that must be held at VCC or GND logic levels. |
| 11 | A | input | Channel-select input A, a binary address bit that must be held at VCC or GND logic levels. |
| 12 | X3 | passive | Analog input/output channel 3 of the multiplexer, with the analog signal limited to the range VEE to VCC. |
| 13 | X0 | passive | Analog input/output channel 0 of the multiplexer, with the analog signal limited to the range VEE to VCC. |
| 14 | X1 | passive | Analog input/output channel 1 of the multiplexer, with the analog signal limited to the range VEE to VCC. |
| 15 | X2 | passive | Analog input/output channel 2 of the multiplexer, with the analog signal limited to the range VEE to VCC. |
| 16 | VCC | power_in | Positive supply, 2.0 to 6.0 V relative to GND for digital control and 2.0 to 12.0 V relative to VEE for the analog switches. |
