SN74HC4051DTR from XBLW, in a SOP-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 | Y4 | passive | Independent analog input or output for channel 4. |
| 2 | Y6 | passive | Independent analog input or output for channel 6. |
| 3 | Z | passive | Common analog output or input of the switch. |
| 4 | Y7 | passive | Independent analog input or output for channel 7. |
| 5 | Y5 | passive | Independent analog input or output for channel 5. |
| 6 | ~{E} | input | Active-LOW enable input; when HIGH all switches are turned off. |
| 7 | VEE | power_in | Negative supply voltage for the analog switches. |
| 8 | GND | power_in | Ground supply voltage. |
| 9 | S2 | input | Select input S2 (most significant bit) choosing which Y channel connects to Z. |
| 10 | S1 | input | Select input S1 choosing which Y channel connects to Z. |
| 11 | S0 | input | Select input S0 (least significant bit) choosing which Y channel connects to Z. |
| 12 | Y3 | passive | Independent analog input or output for channel 3. |
| 13 | Y0 | passive | Independent analog input or output for channel 0. |
| 14 | Y1 | passive | Independent analog input or output for channel 1. |
