SN74HC151QDRQ1 from Texas Instruments, in a SOIC-16. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | D3 | input | Data input D3; selected by address lines A, B, C and routed to the outputs when G is low. |
| 2 | D2 | input | Data input D2; selected by address lines A, B, C and routed to the outputs when G is low. |
| 3 | D1 | input | Data input D1; selected by address lines A, B, C and routed to the outputs when G is low. |
| 4 | D0 | input | Data input D0; selected by address lines A, B, C and routed to the outputs when G is low. |
| 5 | Y | output | Multiplexer true output; reflects the level of the data input selected by A, B, C, or forced low when G is high. |
| 6 | W | output | Multiplexer complementary output; provides the inverse of the selected data input, or forced high when G is high. |
| 7 | G | input | Strobe (enable) input; must be held at a low logic level to enable data selection, a high level forces W high and Y low. |
| 8 | GND | power_in | Ground reference for the device. |
| 9 | C | input | Binary select input C, part of the A/B/C address that chooses one of the eight D inputs. |
| 10 | B | input | Binary select input B, part of the A/B/C address that chooses one of the eight D inputs. |
| 11 | A | input | Binary select input A, part of the A/B/C address that chooses one of the eight D inputs. |
| 12 | D7 | input | Data input D7; selected by address lines A, B, C and routed to the outputs when G is low. |
| 13 | D6 | input | Data input D6; selected by address lines A, B, C and routed to the outputs when G is low. |
| 14 | D5 | input | Data input D5; selected by address lines A, B, C and routed to the outputs when G is low. |
| 15 | D4 | input | Data input D4; selected by address lines A, B, C and routed to the outputs when G is low. |
| 16 | VCC | power_in | Supply voltage pin; recommended operating range 2 V to 6 V. |
