74HC4052D from Nexperia, in a SOIC-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	2Y0	bidirectional	Switch 2 independent input/output channel 0. Analog/digital signal path to/from common terminal 2Z when selected (S1=L, S0=L, E=L).
2	2Y2	bidirectional	Switch 2 independent input/output channel 2. Analog/digital signal path to/from common terminal 2Z when selected (S1=H, S0=L, E=L).
3	2Z	bidirectional	Switch 2 common input/output. Connects to the selected 2Y0..2Y3 channel via the analog switch (typ. 70 ohm ON-resistance at VCC-VEE = 9 V).
4	2Y3	bidirectional	Switch 2 independent input/output channel 3. Analog/digital signal path to/from common terminal 2Z when selected (S1=H, S0=H, E=L).
5	2Y1	bidirectional	Switch 2 independent input/output channel 1. Analog/digital signal path to/from common terminal 2Z when selected (S1=L, S0=H, E=L).
6	E	input	Enable input, active LOW. When E is HIGH, all switches are OFF (no channel connected). When E is LOW, S0/S1 select which nYx is connected to nZ.
7	VEE	power_in	Negative analog supply voltage. Sets the lower rail for analog signals through the switches (may be below GND to allow bipolar analog signals down to -5 V). VCC - VEE range 2.0 V to 10.0 V.
8	GND	power_in	Digital ground reference (0 V) for the logic (E, S0, S1). All voltages in the datasheet are referenced to VEE = GND.
9	S1	input	Channel-select logic input, MSB. Together with S0 selects one of four channels (nY0..nY3) common to both switches. HC: CMOS input levels; HCT: TTL input levels.
10	S0	input	Channel-select logic input, LSB. Together with S1 selects one of four channels (nY0..nY3) common to both switches.
11	1Y3	bidirectional	Switch 1 independent input/output channel 3. Analog/digital signal path to/from common terminal 1Z when selected (S1=H, S0=H, E=L).
12	1Y0	bidirectional	Switch 1 independent input/output channel 0. Analog/digital signal path to/from common terminal 1Z when selected (S1=L, S0=L, E=L).
13	1Z	bidirectional	Switch 1 common input/output. Connects to the selected 1Y0..1Y3 channel via the analog switch (typ. 70 ohm ON-resistance at VCC-VEE = 9 V).
14	1Y1	bidirectional	Switch 1 independent input/output channel 1. Analog/digital signal path to/from common terminal 1Z when selected (S1=L, S0=H, E=L).
15	1Y2	bidirectional	Switch 1 independent input/output channel 2. Analog/digital signal path to/from common terminal 1Z when selected (S1=H, S0=L, E=L).
16	VCC	power_in	Positive supply voltage. 74HC4052: 2.0 V to 10.0 V; 74HCT4052: 4.5 V to 5.5 V (referenced to GND). VCC - VEE must be within 2.0 V to 10.0 V.

3D model downloads

Two STEP files. Same geometry, different body top:

File	Size	Use it when
`74hc4052d.step`	217 KB	You want the bare part, or you mark your own boards.
`74hc4052d-etched.step`	2.2 MB	You want the part with `74HC4052D` already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 561 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.
