SL74LS161 Synchronous 4 Bit Counters; Binary, Direct Reset This synchronous, presettable 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 change conicident with each other when so instructed by the count-enable i.
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 change conicident 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 (positivegoing) edge of the clock input wave form. This counter is fully programmable; that is the outputs may be preset .
