Working Principles

The CD40257BPWRE4 operates based on the principle of multiplexing and demultiplexing. It uses the address inputs (A0-A3) to select one of the eight data inputs (B, C, D) and routes it to the output (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.
