SN74LV4051ATDREP 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 switch terminal for channel 4, selected when INH is low and C=H, B=L, A=L; each channel passes signals up to 5.5 V (peak) in either direction. |
| 2 | Y6 | passive | Analog switch terminal for channel 6, selected when INH is low and C=H, B=H, A=L; each channel passes signals up to 5.5 V (peak) in either direction. |
| 3 | COM | passive | Common analog switch terminal that connects to the selected channel when INH is low; switch I/O voltage is limited to −0.5 V to VCC + 0.5 V and switch through current to ±25 mA. |
| 4 | Y7 | passive | Analog switch terminal for channel 7, selected when INH is low and C=H, B=H, A=H; each channel passes signals up to 5.5 V (peak) in either direction. |
| 5 | Y5 | passive | Analog switch terminal for channel 5, selected when INH is low and C=H, B=L, A=H; each channel passes signals up to 5.5 V (peak) in either direction. |
| 6 | INH | input | Active-high inhibit control; when high, all switches are open and no channel is selected, with control inputs rated 0 V to 5.5 V. |
| 7 | GND | power_in | Ground reference pin for the device. |
| 8 | GND | power_in | Ground reference pin for the device (second GND pin, tied with pin 7 in the datasheet figure). |
| 9 | C | input | Most significant channel-select bit, used with B and A to choose one of the eight channels; control input rated 0 V to 5.5 V. |
| 10 | B | input | Middle channel-select bit, used with C and A to choose one of the eight channels; control input rated 0 V to 5.5 V. |
| 11 | A | input | Least significant channel-select bit, used with C and B to choose one of the eight channels; control input rated 0 V to 5.5 V. |
| 12 | Y3 | passive | Analog switch terminal for channel 3, selected when INH is low and C=L, B=H, A=H; each channel passes signals up to 5.5 V (peak) in either direction. |
| 13 | Y0 | passive | Analog switch terminal for channel 0, selected when INH is low and C=L, B=L, A=L; each channel passes signals up to 5.5 V (peak) in either direction. |
| 14 | Y1 | passive | Analog switch terminal for channel 1, selected when INH is low and C=L, B=L, A=H; each channel passes signals up to 5.5 V (peak) in either direction. |
| 15 | Y2 | passive | Analog switch terminal for channel 2, selected when INH is low and C=L, B=H, A=L; each channel passes signals up to 5.5 V (peak) in either direction. |
| 16 | VCC | power_in | Positive supply pin; the datasheet specifies VCC of 2 V to 5.5 V. |
