74VHC4052AFT from TOSHIBA, in a TSSOP-16-175mil. 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	0Y	bidirectional	Y-bank channel 0 analog switch I/O. Bidirectional analog signal port; connected to Y-COM when A=L, B=L and INH=L. Vs range 0 to Vcc; typical Ron 24 Ω at Vcc = 4.5 V.
2	2Y	bidirectional	Y-bank channel 2 analog switch I/O. Selected when A=L, B=H and INH=L. Vs range 0 to Vcc.
3	Y-COM	bidirectional	Common (pole) terminal of the Y-bank 4:1 analog switch. Connects to one of 0Y..3Y as selected by A/B when INH=L; high-impedance to all when INH=H.
4	3Y	bidirectional	Y-bank channel 3 analog switch I/O. Selected when A=H, B=H and INH=L. Vs range 0 to Vcc.
5	1Y	bidirectional	Y-bank channel 1 analog switch I/O. Selected when A=H, B=L and INH=L. Vs range 0 to Vcc.
6	INH	input	Active-high inhibit / enable input. INH=H disables both banks (all channels OFF, COM pins float); INH=L allows A/B to select one of the four channels per bank. Digital CMOS input; VIH ≥ 2.0 V at Vcc = 3.0 V.
7	GND	power_in	Ground / 0 V reference. Tie to system ground; must be the most-negative voltage seen by any analog switch signal.
8	GND	power_in	Ground / 0 V reference (second GND pin). Both GND pins should be tied together to the system ground plane.
9	B	input	Channel-select input B (MSB of the 2-bit channel address, shared across both X and Y banks). Digital CMOS input; VIH ≥ 2.0 V at Vcc = 3.0 V. Note: the 74VHC4052 uses only A and B (no C select).
10	A	input	Channel-select input A (LSB of the 2-bit channel address, shared across both X and Y banks). Digital CMOS input; VIH ≥ 2.0 V at Vcc = 3.0 V.
11	3X	bidirectional	X-bank channel 3 analog switch I/O. Selected when A=H, B=H and INH=L. Vs range 0 to Vcc.
12	0X	bidirectional	X-bank channel 0 analog switch I/O. Selected when A=L, B=L and INH=L. Vs range 0 to Vcc.
13	X-COM	bidirectional	Common (pole) terminal of the X-bank 4:1 analog switch. Connects to one of 0X..3X as selected by A/B when INH=L; high-impedance when INH=H.
14	1X	bidirectional	X-bank channel 1 analog switch I/O. Selected when A=H, B=L and INH=L. Vs range 0 to Vcc.
15	2X	bidirectional	X-bank channel 2 analog switch I/O. Selected when A=L, B=H and INH=L. Vs range 0 to Vcc.
16	VCC	power_in	Positive supply voltage. Operating range 2.0 V to 5.5 V (absolute max 7.0 V). Sets the upper rail of the analog switch signal range and the digital control input thresholds. Decouple to GND with 0.1 μF close to the pin.

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74vhc4052aft.step`	205 KB	You want the bare part, or you mark your own boards.
`74vhc4052aft-etched.step`	2.3 MB	You want the part with `74VHC4052AFT` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 602 faces against 255 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.
