Working Principles

The CD74HCT253M96 operates based on the principles of multiplexing and demultiplexing. It uses select inputs (S1, S2, S3, S4) to choose one of the four input signals (A1, A2, B1, B2) and route it to the output line (Y). The enable input (E) controls the operation of the IC. When E is high, the selected input is passed to the output. When E is low, the output is disabled.
