74AHC1G86SE-7 from Diodes Incorporated, in a SOT-353. 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	A	input	Data input A of the 2-input XOR gate. CMOS/Schmitt-trigger logic input, VIH ≥ 3.85 V at VCC = 5.5 V; input current ±1 µA typ.
2	B	input	Data input B of the 2-input XOR gate. CMOS/Schmitt-trigger logic input, VIH ≥ 3.85 V at VCC = 5.5 V; input current ±1 µA typ.
3	GND	power_in	Ground reference (0 V). Continuous current through GND rated up to -50 mA absolute maximum.
4	Y	output	Push-pull data output, Y = A ⊕ B. Drives ±8 mA at VCC = 5 V ±0.5 V, or ±4 mA at VCC = 3.3 V ±0.3 V.
5	VCC	power_in	Positive supply voltage, 2.0 V to 5.5 V operating range. Continuous VCC current rated up to 50 mA absolute maximum; typical ICC = 1 µA at 5.5 V.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74ahc1g86se-7.step`	87 KB	You want the bare part, or you mark your own boards.
`74ahc1g86se-7-etched.step`	2.2 MB	You want the part with `74AHC1G86SE-7` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 542 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.
