Bi Directional Buffer 74LS245 This types of bi directional buffer is required for data bus as it has to function as bi directional bus. The logic diagram of such buffer is shown in figure. The direction of data flow is controlled by Dir pin. When DIR is high data flow from A bus to B bus when DIR is low data flow from B to A .
1) Draw the state diagram for the state machine described by Table 7.5 in the text. Note, the table shows the transition to the next state S* from the current state S for the next
Suppose that the x rays are emitted from a focal spot isotropically. The photon flux is 3.28 x 10 6 photons mm -2 sec -1 at a distance of 0.75 m from the focal spot. What is the
