DM9316N Synchronous 4-Bit Counter

Product Description:

The DM9316N Synchronous 4-Bit Counter is a presetable counter that features an internal carry look-ahead for application in high-speed counting designs. 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 simultaneously 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 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.
