SN74LV4051ATDRQ1 from Texas Instruments, 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 | Y4 | passive | Analog channel 4 of the multiplexer, connected to COM when INH is low and C-B-A = 100; in demultiplexer use it is an output. |
| 2 | Y6 | passive | Analog channel 6 of the multiplexer, connected to COM when INH is low and C-B-A = 110; in demultiplexer use it is an output. |
| 3 | COM | passive | Common analog terminal of the multiplexer, the output in multiplexer mode and the input in demultiplexer mode. |
| 4 | Y7 | passive | Analog channel 7 of the multiplexer, connected to COM when INH is low and C-B-A = 111; in demultiplexer use it is an output. |
| 5 | Y5 | passive | Analog channel 5 of the multiplexer, connected to COM when INH is low and C-B-A = 101; in demultiplexer use it is an output. |
| 6 | INH | input | Enable input for the switch outputs: logic low turns the outputs on and logic high turns them off (no channel selected). |
| 7 | GND | power_in | Ground reference pin. |
| 8 | GND | power_in | Ground reference pin. |
| 9 | C | input | Selector line (most significant bit) for choosing the active channel; see the Function Table in section 7.4. |
| 10 | B | input | Selector line (middle bit) for choosing the active channel; see the Function Table in section 7.4. |
| 11 | A | input | Selector line (least significant bit) for choosing the active channel; see the Function Table in section 7.4. |
| 12 | Y3 | passive | Analog channel 3 of the multiplexer, connected to COM when INH is low and C-B-A = 011; in demultiplexer use it is an output. |
| 13 | Y0 | passive | Analog channel 0 of the multiplexer, connected to COM when INH is low and C-B-A = 000; in demultiplexer use it is an output. |
| 14 | Y1 | passive | Analog channel 1 of the multiplexer, connected to COM when INH is low and C-B-A = 001; in demultiplexer use it is an output. |
| 15 | Y2 | passive | Analog channel 2 of the multiplexer, connected to COM when INH is low and C-B-A = 010; in demultiplexer use it is an output. |
| 16 | VCC | power_in | Device supply input; the recommended operating range is 1.65 V to 5.5 V. |
