SN74LVC2G34DBVR from Texas Instruments, in a SOT-23-6. 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 input. CMOS logic input, 5.5 V tolerant regardless of VCC. Threshold set by VIH/VIL versus VCC (e.g. VIH ≥ 2 V, VIL ≤ 0.8 V at VCC = 3 V).
6	1Y	output	Buffer 1 output; Y = A. Push-pull CMOS output rated ±24 mA at VCC = 3.3 V (up to ±32 mA at 4.5 V). Must not be pulled above VCC under normal operation.
3	2A	input	Buffer 2 input. CMOS logic input, 5.5 V tolerant regardless of VCC. Same VIH/VIL thresholds as 1A.
4	2Y	output	Buffer 2 output; Y = A. Push-pull CMOS output rated ±24 mA at VCC = 3.3 V. Balanced output drive matches 1Y.
2	GND	power_in	Device ground reference. Return path for supply and output currents; total continuous current through VCC or GND must not exceed ±100 mA.
5	VCC	power_in	Positive supply, 1.65 V to 5.5 V operating (1.5 V minimum for data retention only). Requires a 0.1 µF bypass capacitor placed as close to the pin as possible.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc2g34dbvr.step`	97 KB	You want the bare part, or you mark your own boards.
`sn74lvc2g34dbvr-etched.step`	2.4 MB	You want the part with `SN74LVC2G34DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 604 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.
