Working Principles

The SN74HC4851PWRG4 is an analog multiplexer/demultiplexer that operates by selectively connecting one of the eight input channels to the output. This selection is controlled by the address inputs (A0-A3) and the enable input (EN). The device also features an inhibit input (INH) that can be used to disable all switches simultaneously.

When a specific channel is selected, the corresponding switch connects the input to the output. The break-before-make switching action ensures that there is no momentary short circuit during the transition between channels.
