$1\mathrm{.}4$ Storing Data via a bi$-$directional Bus

Now, a bi$-$directional bus, which is connected to components of the type $74$LS$374,$ is realized. The first driver is supposed to store the $8-$bit word $(10101010)($D$1$ D$2...$ D$7$ D$8),$ the second driver $(10010010),$ the third driver $(11100011)$ and the fourth driver $(00100011)$ and afterwards it is supposed to be read out

Figure $1$: Data Transfer on a Bus

Q$15$: In which state of the output control can data be read out of the component?

Q$16$: Derive the required patterns for the inputs to solve the problem that was posed in the beginning of the chapter $1\mathrm{.}4$ and explain important simulation steps.
