SN74AHCT1G04DCKR from Texas Instruments, in a SC-70-5. 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. Leave floating or tie to a static level; the pin has no electrical function inside the device. |
| 2 | A | input | Logic input A to the inverter. TTL-voltage compatible: VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Output Y is the logical inversion of this input. |
| 3 | GND | power_in | Device ground reference (0 V). All input/output voltages are referenced to this pin. |
| 4 | Y | output | Inverter output Y = /A. Push-pull CMOS output rated ±8 mA drive at VCC = 5 V (IOH = -8 mA, IOL = 8 mA); VOH ≥ 3.94 V typ and VOL ≤ 0.36 V typ at 4.5 V. |
| 5 | VCC | power_in | Positive supply pin. Recommended operating range 4.5 V to 5.5 V (absolute max 7 V). Decouple to GND with a 0.1 µF ceramic capacitor close to the device. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 641 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.
