SN74LVC2G86DCUR from Texas Instruments, in a VSSOP-8. 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	Gate 1 input A. CMOS logic input; part of the first XOR gate (Y = A XOR B). VIH/VIL scale with VCC (e.g., VIH = 2 V min at VCC = 3.0-3.6 V). Input voltage tolerated up to 5.5 V regardless of VCC.
2	1B	input	Gate 1 input B. CMOS logic input; second input of the first XOR gate. 5.5 V tolerant input; unused inputs must be tied to VCC or GND.
3	2Y	output	Gate 2 output. CMOS push-pull output of the second XOR gate (Y = 2A XOR 2B). Drives ±24 mA at VCC = 3.3 V (±32 mA at 4.5 V; ±4 mA at 1.65 V).
4	GND	power_in	Ground reference (0 V) for the device. Continuous current through GND is limited to ±100 mA.
5	2A	input	Gate 2 input A. CMOS logic input; first input of the second XOR gate. 5.5 V tolerant.
6	2B	input	Gate 2 input B. CMOS logic input; second input of the second XOR gate. 5.5 V tolerant; tie unused inputs to VCC or GND.
7	1Y	output	Gate 1 output. CMOS push-pull output of the first XOR gate (Y = 1A XOR 1B). Drives ±24 mA at VCC = 3.3 V.
8	VCC	power_in	Positive supply input. Operating range 1.65 V to 5.5 V (data retention down to 1.5 V). Bypass with a local ceramic capacitor to GND. Absolute maximum 6.5 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc2g86dcur.step`	122 KB	You want the bare part, or you mark your own boards.
`sn74lvc2g86dcur-etched.step`	3.0 MB	You want the part with `SN74LVC2G86DCUR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 716 faces against 147 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.
