Working Principles

The SN74CBT3251DE4 is a digital multiplexer/demultiplexer IC that allows the selection of one of eight input channels to be routed to a single output. It operates based on the principle of break-before-make switching, ensuring that only one channel is active at a time to prevent signal interference.

The control inputs (A0, A1, A2) determine which channel is selected, while the data inputs (B0, B1) provide the input signals to be multiplexed. The output enable input (OE) enables or disables the output, allowing for easy control of the signal flow.
