74F543 Overview
The 74F543 and 74F544 contain two sets of eight D-type latches, with separate input and controls for each set. For data flow from A to B, for example, the A-to-B Enable (EAB) input must be Low in order to enter data from A0 - A7 or take data from B0 - B7, as indicated in the Function Table. With EAB Low, a Low signal on the A-to-B Latch Enable (LEAB) input makes the A-to-B latches transparent;.
