CD4052BM from HGSEMI, in a SOP-16. 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	Y0	bidirectional	Y-side analog channel 0. Bidirectional analog switch terminal; connects to COMY when A=0,B=0 and INH=0. On-resistance ~60 Ω typ @ VDD-VSS=15 V.
2	Y2	bidirectional	Y-side analog channel 2. Connects to COMY when A=0,B=1 and INH=0.
3	COMY	bidirectional	Y common terminal (Y OUT/IN). Shared node for the Y-side 4:1 mux; routes to Y0..Y3 based on A/B when INH=0.
4	Y3	bidirectional	Y-side analog channel 3. Connects to COMY when A=1,B=1 and INH=0.
5	Y1	bidirectional	Y-side analog channel 1. Connects to COMY when A=1,B=0 and INH=0.
6	INH	input	Inhibit / enable control input. When INH=high (VDD) all channels are OFF (high-Z); when INH=low, the A/B address selects one active channel per side. Digital logic level referenced to VSS.
7	VEE	power_in	Analog negative supply for the switch. Sets the lower rail of the analog signal range; VDD-VEE ≤ 15 V. Tie to VSS for unipolar analog signals.
8	VSS	power_in	Digital/logic ground and the reference for A, B, INH logic levels.
9	B	input	Binary address input B (bit 1) selecting which of the 4 X and Y channels is ON when INH=low. VIH ≥ 11 V typ @ VDD=15 V; VIL ≤ 4 V.
10	A	input	Binary address input A (bit 0) selecting which of the 4 X and Y channels is ON when INH=low.
11	X3	bidirectional	X-side analog channel 3. Connects to COMX when A=1,B=1 and INH=0.
12	X0	bidirectional	X-side analog channel 0. Connects to COMX when A=0,B=0 and INH=0.
13	COMX	bidirectional	X common terminal (X OUT/IN). Shared node for the X-side 4:1 mux; routes to X0..X3 based on A/B when INH=0.
14	X1	bidirectional	X-side analog channel 1. Connects to COMX when A=1,B=0 and INH=0.
15	X2	bidirectional	X-side analog channel 2. Connects to COMX when A=0,B=1 and INH=0.
16	VDD	power_in	Positive supply. VDD-VSS operating range 3-15 V (18 V absolute max). Bypass with 0.1 µF to VSS.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`cd4052bm.step`	217 KB	You want the bare part, or you mark your own boards.
`cd4052bm-etched.step`	2.3 MB	You want the part with `CD4052BM` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 569 faces against 267 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.
