FUNCTIONAL DESCRIPTION
The 74ABT161543 contains two sets of eight D-type latches, with
separate control pins for each set. Using data flow from A to B as an
example, when the A-to-B Enable (nEAB) input and the A-to-B Latch
Enable (nLEAB) input are Low the A-to-B path is transparent.
A subsequent Low-to-High transition of the nLEAB signal puts the A
data into the latches where it is stored and the B outputs no longer
change with the A inputs. With EAB and nOEAB both Low, the
3-State B output buffers are active and display the data present at
the outputs of the A latches.
Control of data flow from B to A is similar, but using the nEBA,
nLEBA, and nOEBA inputs.
