CD74HCT4051M96 from Texas Instruments, 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 A4 bidirectional Analog channel 4 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 100 and Enable is asserted low.
2 A6 bidirectional Analog channel 6 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 110 and Enable is asserted low.
3 COM bidirectional Common analog out/in. Shared switch terminal that connects to one of the eight A0-A7 channels selected by S0-S2. Analog switch is bidirectional so this pin can act as input or output.
4 A7 bidirectional Analog channel 7 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 111 and Enable is asserted low.
5 A5 bidirectional Analog channel 5 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 101 and Enable is asserted low.
6 ~{E} input Active-low enable input. When high, all eight analog switches are disabled (open); when low, the channel selected by S0-S2 is connected to COM. HCT logic thresholds: VIL = 0.8 V max, VIH = 2 V min.
7 VEE power_in Negative analog supply. Establishes the lower limit of the analog switch voltage range; VCC-VEE may be up to 10 V for HCT devices. Tie to GND for single-supply operation.
8 GND power_in Digital ground reference for logic inputs (S0-S2, E) and for the internal level-conversion circuitry.
9 S2 input Channel select bit 2 (MSB) of the 3-bit binary address selecting one of eight channels A0-A7. HCT-level input: VIL = 0.8 V max, VIH = 2 V min.
10 S1 input Channel select bit 1 of the 3-bit binary address selecting one of eight channels A0-A7. HCT-level input: VIL = 0.8 V max, VIH = 2 V min.
11 S0 input Channel select bit 0 (LSB) of the 3-bit binary address selecting one of eight channels A0-A7. HCT-level input: VIL = 0.8 V max, VIH = 2 V min.
12 A3 bidirectional Analog channel 3 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 011 and Enable is asserted low.
13 A0 bidirectional Analog channel 0 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 000 and Enable is asserted low.
14 A1 bidirectional Analog channel 1 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 001 and Enable is asserted low.
15 A2 bidirectional Analog channel 2 in/out. Bidirectional analog switch terminal, connected to the COM pin when S2:S0 = 010 and Enable is asserted low.
16 VCC power_in Positive digital/analog supply, 4.5 V to 5.5 V for HCT variants. Sets the upper limit of the switch voltage range; VCC-VEE up to 10 V permitted.
