Working Principles

The 74HC4067BQ,118 is a CMOS analog multiplexer/demultiplexer IC. It uses a combination of control signals (S0-S3) to select one of the 16 input channels and route it to the output pin (Y0-Y15). The enable signal (E) controls the on/off state of the IC. When enabled, the selected channel is connected to the output pin, allowing the transmission of analog signals.
