Working Principles

SN74LS155ANSR works by receiving input signals on the address lines (A0-A3) and enabling the appropriate output lines based on the input combination. The enable inputs (E1 and E2) control the operation of the decoder/demultiplexer. When enabled, the IC decodes the input lines and activates the corresponding output lines. The selected output line carries the demultiplexed data from the input lines.
