Working Principles

SN74HC4851DGVR operates based on the principle of multiplexing and demultiplexing analog signals. It uses a combination of select inputs (S0-S3) to choose the desired channel and an enable input (E) to control the switching action. When a specific channel is selected, the corresponding output (Y0-Y7) carries the analog signal present at that channel. The break-before-make switching action ensures that there are no short-circuits during the switching process.
