Pinout

Pin Name Type Function
1 CH A4 bidirectional Analog channel 4 input/output, connected to COM when E is low and S2=H, S1=L, S0=L.
2 CH A6 bidirectional Analog channel 6 input/output, connected to COM when E is low and S2=H, S1=H, S0=L.
3 COM OUT/IN bidirectional Common analog output/input that connects to whichever channel is selected by S2, S1, S0 while E is low.
4 CH A7 bidirectional Analog channel 7 input/output, connected to COM when E is low and S2=H, S1=H, S0=H.
5 CH A5 bidirectional Analog channel 5 input/output, connected to COM when E is low and S2=H, S1=L, S0=H.
6 E input Active-low enable input; when high it disables all switches into the off state.
7 VEE power_in Negative power supply input; recommended range is 0 V to -6 V, and VCC - VEE must stay within 2 V to 10 V.
8 GND power_in Ground reference for all voltages on the device.
9 S2 input Channel select 2 binary address input (most significant bit) for choosing among channels 0 to 7.
10 S1 input Channel select 1 binary address input for choosing among channels 0 to 7.
11 S0 input Channel select 0 binary address input (least significant bit) for choosing among channels 0 to 7.
12 CH A3 bidirectional Analog channel 3 input/output, connected to COM when E is low and S2=L, S1=H, S0=H.
13 CH A0 bidirectional Analog channel 0 input/output, connected to COM when E is low and S2=L, S1=L, S0=L.
14 CH A1 bidirectional Analog channel 1 input/output, connected to COM when E is low and S2=L, S1=L, S0=H.
15 CH A2 bidirectional Analog channel 2 input/output, connected to COM when E is low and S2=L, S1=H, S0=L.
16 VCC power_in Positive power supply input; recommended VCC is 2 V to 6 V for HC types (4.5 V to 5.5 V for HCT types).
