SN74ALS151DR from Texas Instruments, in a SOP-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 D3 is selected when C, B, A = L, H, H, and its level appears on Y and W while G is low. |
| 2 | D2 | input | Data input D2 is selected when C, B, A = L, H, L, and its level appears on Y and W while G is low. |
| 3 | D1 | input | Data input D1 is selected when C, B, A = L, L, H, and its level appears on Y and W while G is low. |
| 4 | D0 | input | Data input D0 is selected when C, B, A = L, L, L, and its level appears on Y and W while G is low. |
| 5 | Y | output | Output Y follows the selected data input and is forced low when the strobe G is high. |
| 6 | W | output | Output W follows the selected data input and is forced high when the strobe G is high. |
| 7 | G | input | Active-low strobe that must be at a low logic level to enable the data inputs; a high level forces W high and Y low. |
| 8 | GND | power_in | Ground reference pin for the device. |
| 9 | C | input | Binary select input C (most significant select bit) that chooses among D0 to D7 together with B and A. |
| 10 | B | input | Binary select input B that chooses among D0 to D7 together with C and A. |
| 11 | A | input | Binary select input A (least significant select bit) that chooses among D0 to D7 together with B and C. |
| 12 | D7 | input | Data input D7 is selected when C, B, A = H, H, H, and its level appears on Y and W while G is low. |
| 13 | D6 | input | Data input D6 is selected when C, B, A = H, H, L, and its level appears on Y and W while G is low. |
| 14 | D5 | input | Data input D5 is selected when C, B, A = H, L, H, and its level appears on Y and W while G is low. |
| 15 | D4 | input | Data input D4 is selected when C, B, A = H, L, L, and its level appears on Y and W while G is low. |
| 16 | VCC | power_in | Supply voltage, recommended 4.5 V to 5.5 V with 7 V absolute maximum. |
