74HC4053-MS from MSKSEMI, 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 by bidirectional Analog input/output - 'y' terminal of switch B. Signal path is bidirectional between by and the common by/bx terminal (pin 15) when B=1 and INH=0.
2 bx bidirectional Analog input/output - 'x' terminal of switch B. Connected to common pin 15 when B=0 and INH=0.
3 cy bidirectional Analog input/output - 'y' terminal of switch C. Connected to common pin 4 when C=1 and INH=0.
4 cx OR cy bidirectional Common terminal for switch C. Routed to cx (pin 5) or cy (pin 3) depending on control input C, when INH=0.
5 cx bidirectional Analog input/output - 'x' terminal of switch C. Connected to common pin 4 when C=0 and INH=0.
6 INH input Active-high inhibit/enable input. When INH=1, all three switches are OFF (channels disconnected). When INH=0, the A/B/C select inputs route each switch to its x or y terminal.
7 VEE power_in Analog negative supply for the switch signal path. Sets the lower limit of the analog signal range; VDD-VEE up to 15 V (18 V abs max). Typically tied to VSS for single-supply operation.
8 VSS power_in Digital ground / logic reference for the control inputs (A, B, C, INH).
9 C input Digital select input for switch C. C=0 selects cx↔common (pin 4); C=1 selects cy↔common. Ignored when INH=1.
10 B input Digital select input for switch B. B=0 selects bx↔common (pin 15); B=1 selects by↔common. Ignored when INH=1.
11 A input Digital select input for switch A. A=0 selects ax↔common (pin 14); A=1 selects ay↔common. Ignored when INH=1.
12 ax bidirectional Analog input/output - 'x' terminal of switch A. Connected to common pin 14 when A=0 and INH=0.
13 ay bidirectional Analog input/output - 'y' terminal of switch A. Connected to common pin 14 when A=1 and INH=0.
14 ax OR ay bidirectional Common terminal for switch A. Routed to ax (pin 12) or ay (pin 13) depending on control input A, when INH=0.
15 bx OR by bidirectional Common terminal for switch B. Routed to bx (pin 2) or by (pin 1) depending on control input B, when INH=0.
16 VDD power_in Positive supply. VDD-VSS operating range 3 V to 15 V (18 V abs max). Also sets the logic-high level for the A/B/C/INH control inputs.
