74HC08DMT from HGSEMI, in a TSSOP-14. 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 | A1 | input | Input A of gate 1 (AND gate 1). CMOS logic input; VIH >= 4.2V @ VCC=6V. |
| 2 | B1 | input | Input B of gate 1 (AND gate 1). CMOS logic input. |
| 3 | Y1 | output | Output Y of gate 1. Push-pull output, Y1 = A1 AND B1. Drive capability |
| 4 | A2 | input | Input A of gate 2 (AND gate 2). CMOS logic input. |
| 5 | B2 | input | Input B of gate 2 (AND gate 2). CMOS logic input. |
| 6 | Y2 | output | Output Y of gate 2. Push-pull output, Y2 = A2 AND B2. |
| 7 | GND | power_in | Ground reference (0 V). Return for VCC supply current (ICC max 50 mA). |
| 8 | Y3 | output | Output Y of gate 3. Push-pull output, Y3 = A3 AND B3. |
| 9 | A3 | input | Input A of gate 3 (AND gate 3). CMOS logic input. |
| 10 | B3 | input | Input B of gate 3 (AND gate 3). CMOS logic input. |
| 11 | Y4 | output | Output Y of gate 4. Push-pull output, Y4 = A4 AND B4. |
| 12 | A4 | input | Input A of gate 4 (AND gate 4). CMOS logic input. |
| 13 | B4 | input | Input B of gate 4 (AND gate 4). CMOS logic input. |
| 14 | VCC | power_in | Positive supply voltage. Operating range 2.0 V to 6.0 V (absolute max 6.5 V). Quiescent ICC <= 5.5 uA @ VCC=6 V, TA=25 C. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|
74hc08dmt.step |
194 KB | You want the bare part, or you mark your own boards. |

2.1 MB | You want the part with 74HC08DMT already on it. |
The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 528 faces against 237 in the bare model. It survives export, section views, and rendering in any CAD tool, and it drops straight into KiCad or Fusion with no extra setup.
