Buffer Logic
Buffer Logic
Connect the outputs of the buffer state 3 along ......?
(A) Connect the three-state output buffers three together, and add additional logic to implement the function F = A'BC + ABD + AB'D "Suppose C, D and D 'are data entries in the buffer, and A and B pass through logic that generates the enable inputs. (B) design in part (a) conflict-free three-state output? If not, change the design if need to be free of conflict? If not, change the design if necessary to be free of such conflicts.
If C, D and D are the inputs to the buffers, allowing that signals must be (A'B), (AB) and (AB) for buffers C, D and D '. I would be tempted to use a 2 - line demux> 4 to handle this in a single package or as anything gets in the programmable logic and take at least 2 packages. Regards, Dan.
