SN74LVC2G17DCKR from Texas Instruments, in a SC-70-6. 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	1A	input	Schmitt-trigger input to buffer 1. Accepts input voltages up to 5.5 V regardless of VCC; typical positive-going threshold VT+ = 2.0 V and negative-going threshold VT- = 1.3 V at VCC = 3 V.
2	GND	power_in	Device ground reference (0 V).
3	2A	input	Schmitt-trigger input to buffer 2. Accepts input voltages up to 5.5 V regardless of VCC; hysteresis typically 0.4-1.1 V depending on VCC.
4	2Y	output	Buffered non-inverting output of channel 2 (Y = A). Push-pull CMOS output rated ±24 mA at VCC = 3 V (up to ±32 mA at 4.5 V).
5	VCC	power_in	Positive supply voltage, 1.65 V to 5.5 V operating range. Quiescent current ICC ≤ 10 µA.
6	1Y	output	Buffered non-inverting output of channel 1 (Y = A). Push-pull CMOS output rated ±24 mA at VCC = 3 V (up to ±32 mA at 4.5 V).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc2g17dckr.step`	99 KB	You want the bare part, or you mark your own boards.
`sn74lvc2g17dckr-etched.step`	2.3 MB	You want the part with `SN74LVC2G17DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 589 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.
