SN74AHCT1G04DBVR from Texas Instruments, in a SOT-23-5. 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 | NC | unconnected | No internal connection. Pin may be left floating or tied to VCC/GND for mechanical stability. |
| 2 | A | input | Logic input A. TTL-voltage compatible CMOS input (VIH ≥ 2 V, VIL ≤ 0.8 V at VCC = 4.5-5.5 V). Output Y is the logical inverse of this pin. |
| 3 | GND | power_in | Ground reference. Must be connected to the system 0 V rail. |
| 4 | Y | output | Logic output Y = /A. Push-pull CMOS output rated ±8 mA at VCC = 5 V (VOH ≥ 3.94 V, VOL ≤ 0.36 V). |
| 5 | VCC | power_in | Supply voltage input. Recommended operating range 4.5 V to 5.5 V (absolute max 7 V). Bypass with a 0.1 µF ceramic capacitor placed close to the pin. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 600 faces against 102 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.
