Description
This synchronous presettable decade counter features an internal carry look-ahead for cascading in high-speed counting applications. 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-enable inputs and internal gating. This mode of operation helps eliminate the output counting spikes that are normally associated with asynchronous (ripple-clock) counters.
Features
? High Speed Operation
? High Output Current: Fanout of 10 LSTTL Loads
? Wide Operating Voltage: VCC = 2 to 6 V
? Low Input Current: 1 μA max
? Low Quiescent Supply Current: ICC (static) = 4 μA max (Ta = 25°C)
