Working Principles

The CD74HC251M96 operates based on the principles of digital multiplexing and demultiplexing. It uses select inputs (S0, S1, S2) to determine which data input (A0-A7) is routed to the output (Y). The output enable (OE) pin controls the activation of the output. When OE is low, the output is enabled, and the selected data input is passed through. Conversely, when OE is high, the output is disabled, and no data is transmitted.
