CD4011BPWR 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	Gate 1 input A. CMOS logic input, VIH = 3.5 V min at VDD = 5 V. Protected by internal CMOS clamp network to VDD and VSS.
2	1B	input	Gate 1 input B. CMOS logic input, VIH = 3.5 V min at VDD = 5 V. Protected by internal CMOS clamp network to VDD and VSS.
3	1Y	output	Gate 1 output, Y = NAND(1A, 1B). Buffered CMOS output; IOL/IOH typ 1 mA at VDD = 5 V.
4	2Y	output	Gate 2 output, Y = NAND(2A, 2B). Buffered CMOS output; IOL/IOH typ 1 mA at VDD = 5 V.
5	2A	input	Gate 2 input A. CMOS logic input, VIH = 3.5 V min at VDD = 5 V.
6	2B	input	Gate 2 input B. CMOS logic input, VIH = 3.5 V min at VDD = 5 V.
7	VSS	power_in	Negative supply / ground reference. Normally tied to 0 V. All input and output voltages are referenced to this pin.
8	3A	input	Gate 3 input A. CMOS logic input, VIH = 3.5 V min at VDD = 5 V.
9	3B	input	Gate 3 input B. CMOS logic input, VIH = 3.5 V min at VDD = 5 V.
10	3Y	output	Gate 3 output, Y = NAND(3A, 3B). Buffered CMOS output; IOL/IOH typ 1 mA at VDD = 5 V.
11	4Y	output	Gate 4 output, Y = NAND(4A, 4B). Buffered CMOS output; IOL/IOH typ 1 mA at VDD = 5 V.
12	4A	input	Gate 4 input A. CMOS logic input, VIH = 3.5 V min at VDD = 5 V.
13	4B	input	Gate 4 input B. CMOS logic input, VIH = 3.5 V min at VDD = 5 V.
14	VDD	power_in	Positive supply. Recommended operating range 3 V to 18 V (absolute maximum -0.5 V to +20 V referenced to VSS). Bypass to VSS with a local decoupling capacitor.

CAD (KiCad official)

Footprint: Package_SO:TSSOP-14_4.4x5mm_P0.65mm
3D model: TSSOP-14 (KiCad packages3D, STEP)

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cd4011bpwr.step`	194 KB	You want the bare part, or you mark your own boards.
`cd4011bpwr-etched.step`	2.3 MB	You want the part with `CD4011BPWR` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 587 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.
