Working Principles

The SN74CBT3126DR is a digital multiplexer/demultiplexer IC that allows the selection of one of four input channels to be routed to an output line. It operates based on the address inputs (A0 and A1) and the select input (S). When S is low, the device functions as a multiplexer, and when S is high, it acts as a demultiplexer.

The output enable input (OE) controls the data flow. When OE is low, the outputs are enabled, and when OE is high, the outputs are disabled. The bidirectional nature of the IC enables data transmission in both directions, making it suitable for various applications.
