Working Principles

The SN74CB3Q3257DGVR is a quad 2-channel multiplexer/demultiplexer IC. It allows for the selection and routing of signals between two input channels (A and B) and four output channels (Y0, Y1, Y2, and Y3). The channel selection is controlled by the A0, A1, B0, and B1 inputs. The OE (Output Enable) input enables or disables the output channels.

When the appropriate channel select inputs are activated, the selected input signal is routed to the corresponding output channel. The low on-state resistance ensures minimal signal distortion during transmission. The wide supply voltage range allows for compatibility with various systems.
