SN74LVC1G07DCKR 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. May be left floating or tied to GND/VCC for layout convenience.
2	A	input	Logic input to the buffer. Accepts input voltages 0-5.5 V independent of VCC (1.65-5.5 V). VIH is typically 0.7VCC and VIL is 0.3VCC at 4.5-5.5 V VCC. High input impedance CMOS gate.
3	GND	power_in	Ground reference (0 V) for the device. Must be tied to system ground.
4	Y	output	Open-drain non-inverting buffer output. Follows A: when A is high the output is high-impedance (requires external pull-up), when A is low the output pulls to GND. Sinks up to 32 mA (IOL, VCC=4.5 V) and tolerates up to 5.5 V pull-up regardless of VCC. Enables wired-OR/AND and level translation.
5	VCC	power_in	Positive supply voltage input, 1.65 V to 5.5 V recommended operating range. ICC is 10 uA maximum. Bypass with a 0.1 uF ceramic capacitor to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g07dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g07dckr-etched.step`	2.3 MB	You want the part with `SN74LVC1G07DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 586 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.
