TRI-STATE Programmable Binary Counters

These circuits are synchronous, edge-sensitive, fully-programmable 4-bit counters. The counters

feature both conventional totem-pole and TRI-STATE outputs; such that when the outputs are in

the high impedance mode, they can be used to enter data from the bus lines. In addition, the clear

input operates completely independent of all other inputs. During the programming operation, data is

loaded into the ﬂip-ﬂops on the positive-going edge of the clock pulse. To facilitate cascading of these

counters, the MAX COUNT output can be tied directly into the count enable input of the next counter.
