SN74LV4051ATPWREP from Texas Instruments, in a TSSOP-16-175mil. 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 channel 4 terminal; signals up to 5.5 V (peak) can pass in either direction, with switch I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 2 | Y6 | passive | Analog switch channel 6 terminal; signals up to 5.5 V (peak) can pass in either direction, with switch I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 3 | COM | passive | Common analog switch terminal that connects to the one channel Yn selected by A, B and C; I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 4 | Y7 | passive | Analog switch channel 7 terminal; signals up to 5.5 V (peak) can pass in either direction, with switch I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 5 | Y5 | passive | Analog switch channel 5 terminal; signals up to 5.5 V (peak) can pass in either direction, with switch I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 6 | INH | input | Active-high inhibit control: when high (VIH) all channels are off and no channel is selected; control input range is 0 to 5.5 V. |
| 7 | GND | power_in | Ground reference pin; all unused inputs must be held at VCC or GND for proper operation. |
| 8 | GND | power_in | Ground reference pin (second GND pin); all unused inputs must be held at VCC or GND for proper operation. |
| 9 | C | input | Binary channel-select input (most significant bit of the channel address); control input range is 0 to 5.5 V. |
| 10 | B | input | Binary channel-select input (middle bit of the channel address); control input range is 0 to 5.5 V. |
| 11 | A | input | Binary channel-select input (least significant bit of the channel address); control input range is 0 to 5.5 V. |
| 12 | Y3 | passive | Analog switch channel 3 terminal; signals up to 5.5 V (peak) can pass in either direction, with switch I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 13 | Y0 | passive | Analog switch channel 0 terminal; signals up to 5.5 V (peak) can pass in either direction, with switch I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 14 | Y1 | passive | Analog switch channel 1 terminal; signals up to 5.5 V (peak) can pass in either direction, with switch I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 15 | Y2 | passive | Analog switch channel 2 terminal; signals up to 5.5 V (peak) can pass in either direction, with switch I/O limited to −0.5 V to VCC + 0.5 V (5.5 V max). |
| 16 | VCC | power_in | Positive supply pin; recommended operation is 2 V to 5.5 V, and absolute maximum is 7.0 V. |
