CD4011S from GR, 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	A1	input	Input A of NAND gate 1. CMOS logic input; VIH>=3.5V @ VDD=5V, VIL<=1.5V @ VDD=5V. Input current <= 1uA.
2	B1	input	Input B of NAND gate 1. CMOS logic input paired with A1.
3	Y1	output	Output of NAND gate 1: Y1 = NAND(A1, B1). VOH >= 4.95V @ VDD=5V (
4	Y2	output	Output of NAND gate 2: Y2 = NAND(A2, B2). Same drive characteristics as Y1.
5	A2	input	Input A of NAND gate 2. CMOS logic input.
6	B2	input	Input B of NAND gate 2. CMOS logic input paired with A2.
7	VSS	power_in	Negative supply / ground reference (0V). Absolute maximum VDD-VSS = 18V.
8	A3	input	Input A of NAND gate 3. CMOS logic input.
9	B3	input	Input B of NAND gate 3. CMOS logic input paired with A3.
10	Y3	output	Output of NAND gate 3: Y3 = NAND(A3, B3).
11	Y4	output	Output of NAND gate 4: Y4 = NAND(A4, B4).
12	A4	input	Input A of NAND gate 4. CMOS logic input.
13	B4	input	Input B of NAND gate 4. CMOS logic input paired with A4.
14	VDD	power_in	Positive supply. Recommended 2.5V to 15V; absolute maximum -0.5V to +18V referenced to VSS.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cd4011s.step`	195 KB	You want the bare part, or you mark your own boards.
`cd4011s-etched.step`	1.9 MB	You want the part with `CD4011S` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 476 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.
