SN74LVC1G14DCKR 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	N.C.	unconnected	No internal connection. Pin can be connected to any signal or voltage source, including ground; should always be soldered to the board for mechanical retention.
2	A	input	Schmitt-trigger signal input to the inverter. Accepts input voltages up to 5.5 V independent of VCC. Positive-going threshold V_T+ typ 1.5 V and negative-going V_T- typ 0.84 V at VCC = 3 V, giving hysteresis ~0.56 V.
3	GND	power_in	Device ground reference (0 V).
4	Y	output	Inverted CMOS push-pull output, Y = /A. Balanced high-drive output rated ±24 mA at VCC = 3.3 V (up to ±32 mA at 4.5 V). Propagation delay t_pd typ 4.6 ns max at 3.3 V.
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (1.5 V data-retention only). Absolute max 6.5 V. Quiescent ICC max 10 µA.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g14dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g14dckr-etched.step`	2.2 MB	You want the part with `SN74LVC1G14DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 571 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.
