Working Principles

The SN74CBTLV3257DGVR is a digital multiplexer/demultiplexer IC that operates based on the principles of digital logic. It uses the input select pins (S1-S4) to determine which channel's data input/output (I/O1-I/O4) is connected to the common data bus. The output enable pins (OE1-OE4) control whether the respective channel's output is active or in a high-impedance state.

When a specific channel is selected using the select pins, the corresponding data input/output is connected to the common bus, allowing data to be transmitted. The output enable pins can be used to enable or disable the outputs of individual channels, providing flexibility in routing and controlling the flow of digital signals.
