SN74AUP1T08DCKR from Texas Instruments, 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	A	input	Logic input A to the 2-input AND gate. Schmitt-trigger CMOS input accepting 1.8 V LVCMOS levels; VIH/VIL thresholds referenced to VCC. Input current typ 0.1 µA (max 0.5 µA) at VI = 3.6 V or GND.
2	B	input	Logic input B to the 2-input AND gate. Schmitt-trigger CMOS input accepting 1.8 V LVCMOS levels; VIH/VIL thresholds referenced to VCC. Input current typ 0.1 µA (max 0.5 µA) at VI = 3.6 V or GND.
3	GND	power_in	Ground reference for the device. Connect to system ground with a low-impedance return.
4	Y	output	CMOS logic output, Y = A AND B. Output level referenced to VCC (2.3-3.6 V). Drive capability 4 mA at VCC = 3 V (3.1 mA at VCC = 2.3 V); rail-to-rail CMOS swing.
5	VCC	power_in	Positive supply, 2.3 V to 3.6 V (absolute max 4.6 V). Sets the output logic-high level. Supports Ioff partial-power-down when VCC = 0 V. Typical ICC 0.5 µA (max 0.9 µA). Bypass with a local decoupling capacitor to GND.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74aup1t08dckr.step`	87 KB	You want the bare part, or you mark your own boards.
`sn74aup1t08dckr-etched.step`	2.6 MB	You want the part with `SN74AUP1T08DCKR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 648 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.
