Dual 4-bit binary ripple counter
74F393
FEATURES
• Two 4-bit binary counters • Two Master Resets to clear each 4-bit counter individually
DESCRIPTION
The 74F393 is a Dual Ripple Counter with separate Clock (CPn) and Master Reset (MR) inputs to each counter. The two counters are identified by the “a” and “b” suffixes in the pin configuration. The operation of each half of the 74F393 is the same. The counters are triggered by a High-to-Low transition of the Clock (CPa and CPb) inputs. The counter outputs are internally connected to provide Clock inputs to succeeding stages.
