PRESETTABLE BCD/DECADE UP/DOWN COUNTERS PRESETTABLE 4-BIT BINARY UP/DOWN COUNTERS

PRESETTABLE BCD/DECADE UP/DOWN COUNTERS PRESETTABLE 4-BIT BINARY UP/DOWN COUNTERS The SN54/74LS190 is a synchronous UP/DOWN BCD Decade (8421) Counter and the SN54/74LS191 is a synchronous UP/DOWN Modulo-16 Binary Counter. State changes of the counters are synchronous with the LOW-to-HIGH transit

Synchronous Up/Down Decade Counters(single clock line)

Synchronous Up/Down Decade Counters(single clock line) Synchronous operation is provided by having all flip-flops clocked simultaneously so that the output change coincident with each other when so instructed by the steering logic. This mode of operation eliminates the output counting spikes norm
