SN74LVC2G07DCKR 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	Buffer 1 logic input. Accepts input voltages up to 5.5 V regardless of VCC, enabling up/down level translation. VIH/VIL thresholds scale with VCC per the recommended operating conditions.
2	GND	power_in	Device ground reference (0 V).
3	2A	input	Buffer 2 logic input. Accepts input voltages up to 5.5 V regardless of VCC, enabling up/down level translation.
4	2Y	output	Open-drain output of buffer 2 (non-inverting: follows 2A logic level, low-side pull-down only). Requires an external pull-up resistor; the pull-up rail may be up to 5.5 V independent of VCC. Sinks up to 32 mA at VCC = 4.5 V (IOL).
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (1.5 V min for data retention). Bypass with a ceramic capacitor to GND.
6	1Y	output	Open-drain output of buffer 1 (non-inverting: follows 1A logic level, low-side pull-down only). Requires an external pull-up resistor; the pull-up rail may be up to 5.5 V independent of VCC. Sinks up to 32 mA at VCC = 4.5 V (IOL).

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc2g07dckr.step`	99 KB	You want the bare part, or you mark your own boards.
`sn74lvc2g07dckr-etched.step`	2.5 MB	You want the part with `SN74LVC2G07DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 619 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.
