74HC07M from HGSEMI, in a SOP-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 data input. CMOS input with static-discharge protection; drives the open-drain output 1Y.
2	1Y	output	Buffer 1 open-drain data output. Pulls to GND when 1A is low; high-impedance when 1A is high (requires external pull-up to VCC or higher rail).
3	2A	input	Buffer 2 data input. CMOS input with static-discharge protection; drives the open-drain output 2Y.
4	2Y	output	Buffer 2 open-drain data output. Pulls to GND when 2A is low; high-impedance when 2A is high (requires external pull-up).
5	3A	input	Buffer 3 data input. CMOS input with static-discharge protection; drives the open-drain output 3Y.
6	3Y	output	Buffer 3 open-drain data output. Pulls to GND when 3A is low; high-impedance when 3A is high (requires external pull-up).
7	GND	power_in	Ground reference (0 V) for the device.
8	4Y	output	Buffer 4 open-drain data output. Pulls to GND when 4A is low; high-impedance when 4A is high (requires external pull-up).
9	4A	input	Buffer 4 data input. CMOS input with static-discharge protection; drives the open-drain output 4Y.
10	5Y	output	Buffer 5 open-drain data output. Pulls to GND when 5A is low; high-impedance when 5A is high (requires external pull-up).
11	5A	input	Buffer 5 data input. CMOS input with static-discharge protection; drives the open-drain output 5Y.
12	6Y	output	Buffer 6 open-drain data output. Pulls to GND when 6A is low; high-impedance when 6A is high (requires external pull-up).
13	6A	input	Buffer 6 data input. CMOS input with static-discharge protection; drives the open-drain output 6Y.
14	VCC	power_in	Positive supply voltage. Recommended operating range 2 V to 6 V; absolute maximum 7 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74hc07m.step`	195 KB	You want the bare part, or you mark your own boards.
`74hc07m-etched.step`	1.6 MB	You want the part with `74HC07M` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 425 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.
