TC74HC4052AFT from TOSHIBA, in a TSSOP-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 0Y bidirectional Y-bank switch terminal 0. Analog input/output of Y multiplexer channel 0; connected to Y-COM when A=L, B=L and INH=L.
2 2Y bidirectional Y-bank switch terminal 2. Analog input/output of Y multiplexer channel 2; connected to Y-COM when A=L, B=H and INH=L.
3 Y-COM bidirectional Y-bank common terminal. Analog input/output shared by the Y-side 4:1 switch; routed to 0Y/1Y/2Y/3Y per the address (A,B) selection when INH=L.
4 3Y bidirectional Y-bank switch terminal 3. Analog input/output of Y multiplexer channel 3; connected to Y-COM when A=H, B=H and INH=L.
5 1Y bidirectional Y-bank switch terminal 1. Analog input/output of Y multiplexer channel 1; connected to Y-COM when A=H, B=L and INH=L.
6 INH input Active-high inhibit (enable) input. When INH=H all analog switches are OFF (both X and Y banks disconnected); when INH=L the address inputs A,B select the ON channel. Digital input referenced to VCC/GND (0 to VCC).
7 VEE power_in Negative analog supply for the switch bodies. Sets the low limit of the analog signal range; operating range -6 to 0 V, and VCC-VEE must be 2 to 12 V. Tie to GND for unipolar (0..VCC) operation.
8 GND power_in Digital ground / logic reference (0 V). Reference for the control inputs A, B, C (unused on 4052) and INH.
9 B input Address (select) input B - the MSB of the 2-bit channel select shared by both X and Y banks. Digital logic input referenced to VCC/GND. See Truth Table for A,B → channel mapping.
10 A input Address (select) input A - the LSB of the 2-bit channel select shared by both X and Y banks. Digital logic input referenced to VCC/GND. See Truth Table for A,B → channel mapping.
11 3X bidirectional X-bank switch terminal 3. Analog input/output of X multiplexer channel 3; connected to X-COM when A=H, B=H and INH=L.
12 0X bidirectional X-bank switch terminal 0. Analog input/output of X multiplexer channel 0; connected to X-COM when A=L, B=L and INH=L.
13 X-COM bidirectional X-bank common terminal. Analog input/output shared by the X-side 4:1 switch; routed to 0X/1X/2X/3X per the address (A,B) selection when INH=L.
14 1X bidirectional X-bank switch terminal 1. Analog input/output of X multiplexer channel 1; connected to X-COM when A=H, B=L and INH=L.
15 2X bidirectional X-bank switch terminal 2. Analog input/output of X multiplexer channel 2; connected to X-COM when A=L, B=H and INH=L.
16 VCC power_in Positive digital / analog supply, 2 V to 6 V (VCC-VEE ≤ 12 V). Powers the internal logic and sets the upper limit of the analog signal range. Bypass locally with a 0.1 µF ceramic to GND.
