SN74LVC1G04DCKR from UMW, 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 connection. Empty foot with no internal die bond; leave floating or tie to a static net per board convention.
2	A	input	Logic input to the inverter. CMOS-compatible thresholds scale with VCC (VIH ≈ 0.7·VCC, VIL ≈ 0.3·VCC at VCC = 3-5.5 V). Input leakage typically 0.1 µA, absolute max ±5.5 V regardless of VCC.
3	GND	power_in	Device ground / 0 V reference for the logic and output stages.
4	Y	output	Inverted logic output (Y = /A). Push-pull CMOS drive rated up to ±32 mA at VCC = 4.5 V (±16 mA at 3 V, ±8 mA at 2.3 V, ±4 mA at 1.65 V). Swings rail-to-rail into a light load.
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (6.5 V absolute max). Bypass with a local 0.1 µF ceramic to GND. Static ICC ~0.1 µA typical.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g04dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g04dckr-etched.step`	2.4 MB	You want the part with `SN74LVC1G04DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 601 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.
