Working Principles

The SN74CBT3257CPWRE4 is a multiplexer/demultiplexer switch that allows the selection and routing of analog or digital signals between multiple input/output channels. It operates by controlling the channel select inputs (A0, A1, S0, S1) to determine the desired channel configuration. The output enable input (OE) enables or disables the data outputs (Y0-Y3). The break-before-make switching action ensures that only one channel is active at a time, preventing signal interference.
