Working Principles

The TC74HC4051AF(EL,F) is a digital multiplexer/demultiplexer IC that allows the selection of one input from multiple analog signals. It operates based on the principle of CMOS logic, where the control inputs (S0, S1, S2) determine which channel is connected to the output (Y). The E (Enable) pin controls the operation of the IC, while the INH (Inhibit) pin disables all channels when set to a logic low.

When a specific combination of control inputs is applied, the corresponding channel is selected, and the analog signal present at the Z input is routed to the Y output. The break-before-make switching action ensures that there is no overlap or short-circuiting during the transition between channels.
