SN74LVC1G86DCKR from UMW, 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	INB	input	B-input of the 2-input XOR gate. LVCMOS/TTL compatible logic input, tolerant to VIN up to 7 V independent of VCC. VIH = 0.7·VCC (VCC 2.3-5.5 V); input leakage ±1 µA max.
2	INA	input	A-input of the 2-input XOR gate. LVCMOS/TTL compatible logic input, tolerant to VIN up to 7 V independent of VCC. VIH = 0.7·VCC (VCC 2.3-5.5 V); input leakage ±1 µA max.
3	GND	power_in	Ground reference (0 V) for the device. Connect to system ground.
4	Y	output	XOR output (Y = A ⊕ B). Push-pull CMOS output, sinks up to 24 mA (IOL) and sources up to 24 mA (IOH) at VCC=3 V; pullup on this pin may be tied to a rail between 0 and 7 V.
5	VCC	power_in	Positive supply input. Recommended operating range 1.65 V to 5.5 V (absolute max 7 V). Bypass with a 0.1 µF ceramic capacitor to GND close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc1g86dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`sn74lvc1g86dckr-etched.step`	2.6 MB	You want the part with `SN74LVC1G86DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 637 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.
