Synchronous Up / Down Decade Counter (dual clock lines)

Synchronous operation is provided by having all flip-flops clocked simultaneously so that the output change coincidently with each other when so instructed by the steering logic. This mode of operation eliminates the output counting spikes which are normally associated with asynchronous (ripple cl

PRESETTABLE 4-BIT COUNTER

The SN54/74LS192 is an UP/DOWN BCD Decade (8421) Counter and the SN54/74LS193 is an UP/DOWN MODULO-16 Binary Counter. Separate Count Up and Count Down Clocks are used and in either counting mode the circuits operate synchronously. The outputs change state synchronous with the LOW-to-HIGH transitio
