Working Principles
The MC74HC4851ADTR2G operates as an analog multiplexer/demultiplexer by selectively connecting one of the eight input channels to the output. The channel selection is determined by the address inputs (A0-A5), which are decoded internally. The enable input (E) controls the device's operation, allowing the user to enable or disable the multiplexing/demultiplexing function.
When a specific channel is selected, the corresponding analog signal is passed through the IC without significant distortion. The break-before-make switching action ensures that there is no overlap between the previous and new channel connections, preventing signal interference.
