SN74AHCT1G86DBVR from UMW, in a SOT-23-5. 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	A	input	Logic input A of the 2-input XOR gate. TTL-compatible input; VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Input current ±1 µA max.
2	B	input	Logic input B of the 2-input XOR gate. TTL-compatible input; VIH ≥ 2 V, VIL ≤ 0.8 V over VCC = 4.5-5.5 V. Input current ±1 µA max.
3	GND	power_in	Ground reference (0 V) for the device.
4	Y	output	XOR gate output, Y = A ⊕ B. Push-pull CMOS output, 8 mA drive at VCC = 5 V (IOH = −8 mA, IOL = 8 mA); VOH ≥ 3.8 V, VOL ≤ 0.44 V under load.
5	VCC	power_in	Positive supply voltage, 4.5 V to 5.5 V recommended (absolute max 7.0 V). Typical ICC = 1 µA, 10 µA max.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74ahct1g86dbvr.step`	85 KB	You want the bare part, or you mark your own boards.
`sn74ahct1g86dbvr-etched.step`	2.5 MB	You want the part with `SN74AHCT1G86DBVR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 636 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.
