Working Principles

The MC74VHC4051MELG is an analog multiplexer/demultiplexer that allows the selection of one input from multiple sources and routing it to a single output. It operates based on the principle of electronic switching, where the control signals (S0, S1, S2) determine the channel selection. When enabled (E = HIGH), the selected channel connects the input (Y) to the output (Z). The device operates within a specified supply voltage range (2.0V to 6.0V) and provides low on-resistance to minimize signal distortion.
