9316/DM9316 Synchronous 4-Bit Counters

General Description

These synchronous, presettable counters feature an inter-

nal carry look-ahead for application in high-speed counting

designs. The 9316 is a 4-bit binary counter. The carry output

is decoded by means of a NOR gate, thus preventing spikes

during the normal counting mode of operation. Synchronous

operation is provided by having all flip-flops clocked simulta-

neously so that the outputs change coincident with each

other when so instructed by the count-enables inputs and

internal gating. This mode of operating eliminates the output

counting spikes which are normally associated with asyn-

chronous (ripple clock) counters. A buffered clock input trig-

gers the four flip-flops on the rising (positive-going) edge of

the clock input waveform.

The carry look-ahead circuitry provides for cascading coun-

ters for n-bit synchronous applications without additional

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 car-

ry output thus enabled will produce a high-level output pulse

with a duration approximately equal to the high-level portion

of the Q output. 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 may occur

regardless of the logic level in the clock.

Features

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. Low-to-high transitions at the load input are perfectly

acceptable regardless of the logic levels on the clock or

enable inputs. The clear function is asynchronous and a low

level at the clear input sets of the flip-flop outputs low re-

gardless of the levels of clock, load, or enable inputs.
