Working Principles

The MC74LVXT4066MG is a multiplexer/demultiplexer IC that operates as an analog switch. It allows the selection of one input from multiple sources and routes it to the output. The control inputs determine which channel is active, while the inhibit control input can disable all channels simultaneously.

When a specific channel is selected, the corresponding input signal is connected to the output, allowing the transmission of analog or digital signals. The low on-state resistance ensures minimal signal loss during the switching process.
