Working Principles

The MC74HC4051ADTR2G operates by utilizing CMOS technology to control the routing of analog signals. It consists of an 8-channel multiplexer/demultiplexer that can be controlled through the selection inputs (S0, S1, S2) to choose the desired input or output channel. The enable input (E) is used to activate or deactivate the device. When enabled, the selected input is connected to the output pin (Y). The break-before-make switching action ensures that there is no momentary short circuit during the switching process.
