Working Principles

The MM74HC4052N operates based on the principle of analog or digital signal routing through the selection of specific channels. The channel select inputs (S0, S1, S2) determine which input is connected to the output line (Z). The enable input (E) controls the overall operation of the IC.

When a specific channel is selected, the corresponding analog/digital input/output (Y0-Y3) is connected to the output line, allowing the signal to pass through. The break-before-make switching action ensures that there is no overlap or interference between the channels during switching.
