SN74LVC2G04DCKR from Texas Instruments, in a SOT-363-6. 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	INA1	input	Logic input to inverter gate 1. CMOS input, overvoltage tolerant up to 5.5V independent of VCC. VIH ≥ 0.7·VCC (VCC ≥ 2.3V), VIL ≤ 0.3·VCC. Input leakage ±1 µA max.
2	GND	power_in	Ground reference (0 V). Common return for VCC and all logic signals.
3	INA2	input	Logic input to inverter gate 2. CMOS input, overvoltage tolerant up to 5.5V independent of VCC. VIH ≥ 0.7·VCC (VCC ≥ 2.3V), VIL ≤ 0.3·VCC.
4	Y2	output	Inverted logic output of gate 2 (Y2 = /INA2). Push-pull CMOS output with ±24 mA balanced sink/source capability. VOH ≥ VCC−0.1V at 100 µA; VOL ≤ 0.55V at 24 mA (VCC = 3V).
5	VCC	power_in	Positive supply. Operating range 1.65V to 5.5V; absolute maximum 7V. Quiescent supply current ICC ≤ 10 µA. Bypass with a 0.1 µF ceramic capacitor to GND close to the pin.
6	Y1	output	Inverted logic output of gate 1 (Y1 = /INA1). Push-pull CMOS output with ±24 mA balanced sink/source capability. VOH ≥ VCC−0.1V at 100 µA; VOL ≤ 0.55V at 24 mA (VCC = 3V).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc2g04dckr.step`	99 KB	You want the bare part, or you mark your own boards.
`sn74lvc2g04dckr-etched.step`	2.5 MB	You want the part with `SN74LVC2G04DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 634 faces against 117 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.
