SN74LVC3G17DCTR from Texas Instruments, in a MSOP-8-2.8mm. 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 | 1A | input | Schmitt-trigger input for buffer 1. Accepts input voltages up to 5.5 V regardless of VCC. Typical VT+ = 1.5 V, VT- = 0.84 V at VCC = 3 V; hysteresis ~0.56 V. |
| 2 | 3Y | output | Buffered non-inverting output of buffer 3 (Y = A). Drive strength ±24 mA at VCC = 3.3 V; up to ±32 mA at VCC = 4.5 V. |
| 3 | 2A | input | Schmitt-trigger input for buffer 2. Accepts input voltages up to 5.5 V regardless of VCC. Typical hysteresis ~0.56 V at VCC = 3 V. |
| 4 | GND | power_in | Device ground reference (0 V). Return for VCC supply current and output low sink current. |
| 5 | 2Y | output | Buffered non-inverting output of buffer 2 (Y = A). Drive strength ±24 mA at VCC = 3.3 V. |
| 6 | 3A | input | Schmitt-trigger input for buffer 3. Accepts input voltages up to 5.5 V regardless of VCC. |
| 7 | 1Y | output | Buffered non-inverting output of buffer 1 (Y = A). Drive strength ±24 mA at VCC = 3.3 V. |
| 8 | VCC | power_in | Positive supply voltage, 1.65 V to 5.5 V operating range (absolute max 6.5 V). Low quiescent current (ICC max 10 µA). Decouple to GND with a 100 nF ceramic capacitor placed close to the pin. |

Two STEP files. Same geometry, different body top:
| File | Size | Use it when |
|---|---|---|

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 623 faces against 147 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.
