Synchronous
Up-Down Counters
A circuit of a 3-bit synchronous up-down counter and a table of its sequence are shown below. Similar to an asynchronous up-down counter, a synchronous up-down counter also has an up-down control input. It is used to control the direction of the counter through a certain sequence.
An examination of the sequence table shows:

These characteristics are implemented with the AND, OR & NOT logic connected as shown in the logic diagram above.
