Working Principles

The 74HCT4051D-Q100,11 is an analog multiplexer/demultiplexer IC that routes one of the eight input channels to the output based on the binary address inputs (A, B, C). The selected channel's signal is then available at the multiplexer output (Z). The output enable input (E) controls whether the output signal is active or disabled. The IC operates at a low supply voltage and provides fast switching times for efficient data transmission.
