Working Principles

The MC74HC4051ADTR2 operates based on the principle of analog multiplexing. It uses control signals (S0, S1, S2) to select one of the eight input channels and route it to the output pin (Z). The enable signal (EN) enables or disables the operation of the IC. When enabled, the selected input is connected to the output, allowing the signal to pass through. When disabled, the IC disconnects the input from the output, preventing any signal flow.
