SN74HC151PWR from Texas Instruments, in a TSSOP-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 | D3 | input | Data input 3, selected when C B A = L H H; unused inputs must be held at VCC or GND. |
| 2 | D2 | input | Data input 2, selected when C B A = L H L; unused inputs must be held at VCC or GND. |
| 3 | D1 | input | Data input 1, selected when C B A = L L H; unused inputs must be held at VCC or GND. |
| 4 | D0 | input | Data input 0, selected when C B A = L L L; unused inputs must be held at VCC or GND. |
| 5 | Y | output | Standard data output that follows the selected D input, forced low when strobe G is high, with ±6 mA drive at 5 V. |
| 6 | W | output | Inverted data output, forced high when strobe G is high. |
| 7 | G | input | Strobe input, active low; must be at a low logic level to enable the data inputs. |
| 8 | GND | power_in | Ground pin. |
| 9 | C | input | Data select input C (most significant select bit) for choosing one of eight data sources. |
| 10 | B | input | Data select input B for choosing one of eight data sources. |
| 11 | A | input | Data select input A (least significant select bit) for choosing one of eight data sources. |
| 12 | D7 | input | Data input 7, selected when C B A = H H H; unused inputs must be held at VCC or GND. |
| 13 | D6 | input | Data input 6, selected when C B A = H H L; unused inputs must be held at VCC or GND. |
| 14 | D5 | input | Data input 5, selected when C B A = H L H; unused inputs must be held at VCC or GND. |
| 15 | D4 | input | Data input 4, selected when C B A = H L L; unused inputs must be held at VCC or GND. |
| 16 | VCC | power_in | Supply voltage pin, 2 V to 6 V recommended, with a 0.1-μF bypass capacitor placed close to the pin. |
