Synchronous 4-Bit Binary Counters
General Description
These synchronous, presettable counters feature an inter-
nal carry look-ahead for application in high-speed counting
designs. They are 4-bit binary counters. The carry output is
decoded by means of a NOR gate, thus preventing spikes
during the normal counting mode of operation. Synchro-
nous operation is provided by having all flip-flops clocked
simultaneously so that the outputs change coincident with
each other when so instructed by the count enable inputs
and internal gating. This mode of operation eliminates the
output counting spikes which are normally associated with
asynchronous (ripple clock) counters. A buffered clock
input triggers the four flip-flops on the rising (positive-
going) edge of the clock input waveform.
These counters are fully programmable; that is, the outputs
may be preset to either level. As presetting is synchronous,
setting up a LOW level at the load input disables the
counter and causes the outputs to agree with the setup
data after the next clock pulse regardless of the levels of
the enable input.
The carry look-ahead circuitry provides for cascading
counters for n-bit synchronous applications without addi-
tional gating. Instrumental in accomplishing this function
are two count-enable inputs and a ripple carry output. Both
count-enable inputs (P and T) must be HIGH to count, and
input T is fed forward to enable the ripple carry output. The
ripple carry output thus enabled will produce a HIGH-level
output pulse with a duration approximately equal to the
HIGH-level portion of the QA output. This HIGH-level over-
flow ripple carry pulse can be used to enable successive
cascaded stages.
