Working Principles

The MC74HC4851ADWR2G is an analog multiplexer/demultiplexer that routes analog signals from multiple input channels to a single output channel or vice versa. It operates based on the control inputs (S0, S1, S2) and enables (E), which determine the selected channel. The inhibit control input (INH) can be used to disable all channels simultaneously.

When a specific channel is selected, the corresponding input signal is routed to the common output (Z). The IC's low on-resistance ensures minimal signal distortion and loss during the switching process. The high-speed CMOS technology employed in the IC allows for fast and accurate signal routing.
