Working Principles

The SN74CBTLV3257DR is a digital multiplexer/demultiplexer IC that operates by selectively connecting one of the four input/output channels to the common output/input line based on the control signals. The channel select (S) pin determines the direction of data flow, while the enable (EN) pin activates or deactivates the IC's functionality. When a specific channel is enabled, the corresponding control (C) pin controls the connection of the associated data input/output (I/O) pin to the common line.
