A0, A1, A2 (Address Inputs): These three pins are used to select one of the four input channels (D0 to D3). The state of these pins (binary code 000 to 111) determines which data path the multiplexer connects to the output (Z).
S1, S2, S3 (Selection Control Inputs): These three pins allow you to control the switching of the multiplexer. They are used in combination with the address inputs to determine the final data path. The selection logic is set so that the multiplexer switches the channels based on their states.
VSS (GND): This is the ground pin, which should be connected to the ground of the system.
VDD: This pin is the supply voltage pin, where a positive voltage is applied to power the IC. Typical values range from 2V to 6V.
D0 to D3 (Data Channels): These pins are the input/output channels of the multiplexer. Depending on the state of the address and selection pins, one of these channels will be connected to the output pin (Z).
Z (Output Pin): This is the output of the multiplexer. One of the input channels (D0 to D3) is selected based on the address and control input pins and routed to this output.
NC (No Connection): These pins are not connected to any internal circuitry, and are typically unused in the circuit.
