SN74AHC1G09DBVR 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 | A | input | Logic input A of the 2-input positive-AND gate. CMOS input, VIH ranges from 1.5 V (VCC=2 V) to 3.85 V (VCC=5.5 V); VIL ranges from 0.5 V (VCC=2 V) to 1.65 V (VCC=5.5 V). Must not be left floating; tie unused inputs to VCC or GND. |
| 2 | B | input | Logic input B of the 2-input positive-AND gate. CMOS input with same VIH/VIL thresholds as pin A. Must not be left floating; tie unused inputs to VCC or GND. |
| 3 | GND | power_in | Ground reference (0 V) for the device. |
| 4 | Y | output | Open-drain AND-gate output (Y = A * B). Requires an external pull-up resistor to a rail up to VCC + 0.7 V (absolute max). Sinks up to 8 mA at VCC = 4.5 V (VOL <= 0.44 V at 85 degC) or 4 mA at VCC = 3 V. High-Z when either input is high or when output is high in the truth table (H(Z)). |
| 5 | VCC | power_in | Positive supply voltage input. Recommended operating range 2 V to 5.5 V (absolute max 7 V). Bypass with a 0.1 uF capacitor close to the pin. |

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 608 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.
