41. 1-to-4 Data Distributor

• Output Select Analysis: The select lines (S1, S0) target a specific output destination. The chosen output line (Y0, Y1, Y2, or Y3) mirrors the state of the data input (D), while the remaining three unselected lines stay forced at 0.
• Hardware Optimization: The inputs S1 and S0 are routed through NOT gates to create inverted signal paths. These control lines are combined with the data input (D) using four separate AND gates, ensuring that the input signal is only distributed to one output path at a time.

Boolean Equations:

• Y0 = D . ~S1 . ~S0
• Y1 = D . ~S1 . S0
• Y2 = D . S1 . ~S0
• Y3 = D . S1 . S0
