Show how to connect the 74ALS174 so that it operates as a serial shift register with data shifting on each PGT of CP as follows: Serial input \rightarrow Q_{5} \rightarrow Q_{4} \rightarrow Q_{3} \rightarrow Q_{2} \rightarrow Q_{1} \rightarrow Q_{0} . In other words, serial data will enter at D_{5} and will output at Q_{0} .

Looking at Figure 7-67(a), we can see that to connect the six FFs as a serial shift register, we have to connect the Q output of one to the D input of the next so that data is transferred in the required manner. Figure 7-68 shows how this is accomplished. Note that data shifts left to right, with input data applied at D_{5} and output data appearing at Q_{0}.
