Synchronous 4-bit Binary Counter (direct clear)

REJ03D0447–0200

Rev.2.00

Feb.18.2005

This synchronous 4-bit binary counter features an internal carry look-ahead for application in high-speed counting

designs. Synchronous operation is provided by having all flip-flops clocked simultaneously so that the outputs changes

coincident with each other when so instructed by the count-enable inputs and internal gating. This mode of operation

eliminates the output counting spikes that 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. This

counter is fully programmable; that is, the output 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 inputs. Low-to-high transitions at the load input would be avoided when the

clock is low if the enable inputs are high at or before the transition. The clear function is asynchronous and a low level

at the clear input sets all four of the flip-flop outputs low after the next clock pulse, regardless of the levels of the enable

inputs. This synchronous clear allows the count length to be modified easily as decoding the maximum count desired

can be accomplished with one external NAND gate. The gate output is connected to the clear input to synchronously

clear the counter to LLLL. Low-to-high transitions at the clear input should be avoided when the clock is low if the

enable and load inputs are high at or before the transition. The carry look-ahead circuitry provides for cascading

counters for n-bit synchronous applications without additional getting. 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 Q_Aoutput. This high-level overflow ripple

carry pulse can be used to enable successive cascaded stages. High-to-low-level transitions at the enable P or T inputs

should occur only when the clock input is high.
