SN74LVC07APWR from Texas Instruments, in a TSSOP-14. 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	Buffer 1 input. CMOS logic input, VIH/VIL scale with VCC; tolerates up to 5.5 V regardless of VCC.
2	1Y	output	Buffer 1 open-drain output. Requires external pull-up resistor to a rail up to 5.5 V. IOL up to 24 mA at VCC = 4.5 V.
3	2A	input	Buffer 2 input. CMOS logic input, tolerates up to 5.5 V.
4	2Y	output	Buffer 2 open-drain output. Requires external pull-up resistor.
5	3A	input	Buffer 3 input. CMOS logic input, tolerates up to 5.5 V.
6	3Y	output	Buffer 3 open-drain output. Requires external pull-up resistor.
7	GND	power_in	Ground reference pin. Connect to 0 V.
8	4Y	output	Buffer 4 open-drain output. Requires external pull-up resistor.
9	4A	input	Buffer 4 input. CMOS logic input, tolerates up to 5.5 V.
10	5Y	output	Buffer 5 open-drain output. Requires external pull-up resistor.
11	5A	input	Buffer 5 input. CMOS logic input, tolerates up to 5.5 V.
12	6Y	output	Buffer 6 open-drain output. Requires external pull-up resistor.
13	6A	input	Buffer 6 input. CMOS logic input, tolerates up to 5.5 V.
14	VCC	power_in	Positive supply pin. Recommended VCC range 1.65 V to 5.5 V. Bypass with 0.1 uF ceramic capacitor to GND close to the pin.

CAD (KiCad official)

3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`sn74lvc07apwr.step`	194 KB	You want the bare part, or you mark your own boards.
`sn74lvc07apwr-etched.step`	2.4 MB	You want the part with `SN74LVC07APWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 624 faces against 237 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.
