Working Principles

The MC74LVXT4051DTG operates based on CMOS technology, utilizing MOSFET switches to route analog signals. When a specific channel is selected through the control pins (S0-S7), the corresponding switch connects the input signal to the output pin (Y7-Y4). The INH pin can be used to disable all switches simultaneously.

The break-before-make switching action ensures that there is no overlap between the previous and new channel selections, preventing signal distortion or short-circuits during switching.
