MC74HC1G04DFT1G from onsemi, in a SOT-353. 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 connection. Pin is not internally bonded; leave floating or tie to a convenient net.
2	IN A	input	Logic input to the inverter. CMOS-compatible input; VIH min = 0.7VCC, VIL max = 0.3VCC (nominal at VCC = 5 V: 3.15 V / 1.35 V). Input capacitance CIN typ = 5 pF, max 10 pF.
3	GND	power_in	Ground reference (0 V) for the device.
4	OUT Y	output	Inverted logic output (Y = !A). Push-pull CMOS output rated IOH = IOL = 2 mA (symmetrical). VOH min = VCC - 0.1 V at 20 uA load; VOL max = 0.1 V at 20 uA load.
5	VCC	power_in	Positive supply voltage. Recommended operating range 2.0 V to 6.0 V; absolute max 7.0 V. Quiescent supply current ICC max = 1 uA at TA = 25 C.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`mc74hc1g04dft1g.step`	87 KB	You want the bare part, or you mark your own boards.
`mc74hc1g04dft1g-etched.step`	2.3 MB	You want the part with `MC74HC1G04DFT1G` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 580 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.
