Working Principles

The MC74HC4053ADG operates based on the principle of multiplexing and demultiplexing. It uses the select inputs (S1, S2, and S3) to determine which input signal is connected to the output line. The three-state outputs allow for high impedance when not selected, preventing signal interference.

When a specific select input combination is applied, the corresponding input signal is routed to the output line. The break-before-make switching action ensures that there is no overlap or short-circuiting of signals during the switching process.
