HD74LS190P, HD74LS190, Synchronous Up / Down Decade Counter
HD74LS190 Synchronous Up / Down Decade Counter (signal clock line) REJ03D0452 0200 Rev.2.00 Jul.15.2005 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 steering logic.
This mode of operation eliminates the output counting spikes normally associated with asynchronous (ripple clock) counters.
The outputs of the four master-slave flip-flops are triggered on a low-to-high-level
