Part III In Figure 4 we showed a 2-to-1 multiplexer that selects between the two inputs x and y. For this part consider a circuit in which the output m has to be selected from five inputs u, v, w, r, and y. Part a of Figure 6 shows hovw we can build the required 5-to-1 multiplexer by using four 2-to-1 multiplexers. The circuit uses a 3-bit select input s281So and implements the truth table shown in Figure 6b. A circuit symbol for this multiplexer is given in part c of the figure. Recall from Figure 5 that an eight-bit wide 2-to-1 multiplexer can be built by using eight instances of a 2-to-1 multiplexer. Figure 7 applies this concept to define a three-bit wide 5-to-1 multiplexer. It contains three instances of the circuit in Figure 6a PN Part III In Figure 4 we showed a 2-to-1 multiplexer that selects between the two inputs x and y.
