74VHC14MTCX from onsemi, 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	A0	input	Schmitt-trigger input to inverter 0. Positive threshold VP typ 2.2 V and negative threshold VN typ 1.35 V at VCC=4.5 V, giving typ 0.4 V hysteresis. Input leakage ±0.1 µA typ; input can be driven 0 V to 7 V regardless of VCC.
2	O0	output	Inverted CMOS output of gate 0 (O0 = /A0). Drives VOH ≥ 4.4 V at IOH = -50 µA and VOL ≤ 0.1 V at IOL = 50 µA with VCC=4.5 V; guaranteed 4/8 mA drive.
3	A1	input	Schmitt-trigger input to inverter 1. Same electrical behavior as A0.
4	O1	output	Inverted CMOS output of gate 1 (O1 = /A1).
5	A2	input	Schmitt-trigger input to inverter 2.
6	O2	output	Inverted CMOS output of gate 2 (O2 = /A2).
7	GND	power_in	Ground / 0 V reference for the device.
8	O5	output	Inverted CMOS output of gate 5 (O5 = /A5).
9	A5	input	Schmitt-trigger input to inverter 5.
10	O4	output	Inverted CMOS output of gate 4 (O4 = /A4).
11	A4	input	Schmitt-trigger input to inverter 4.
12	O3	output	Inverted CMOS output of gate 3 (O3 = /A3).
13	A3	input	Schmitt-trigger input to inverter 3.
14	VCC	power_in	Positive supply, 2.0 V to 5.5 V recommended (7.0 V absolute max). Quiescent ICC ≤ 20 µA at VCC=5.5 V. Bypass with a 0.1 µF ceramic close to the pin.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74vhc14mtcx.step`	194 KB	You want the bare part, or you mark your own boards.
`74vhc14mtcx-etched.step`	1.9 MB	You want the part with `74VHC14MTCX` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 512 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.
