Working Principles

The SN74CB3T3253DGVR operates as a multiplexer/demultiplexer by utilizing address inputs (A0, A1) to select one of the two data inputs (I0, I1) and route it to the output pin (Y). The select input (S) determines whether the IC functions as a multiplexer or demultiplexer. When S is low, the IC acts as a multiplexer, and when S is high, it functions as a demultiplexer.
