Working Principles

The CD74HC4052PWRG4 operates based on the principle of digital control of analog signals. It uses a combination of select inputs (S0-S5) to determine which channel is active. The inhibit input (INH) can be used to disable all channels simultaneously.

When a specific channel is selected, the corresponding output (Y1-Y4) becomes active, allowing the analog signal to pass through. The break-before-make switching action ensures that there are no short-circuits during the switching process.
