Synchronous 4-Bit Binary Counters
±4-mA Output Drive at 5 V
Low Input Current of 1 µA Max Internal Look-Ahead for Fast Counting Carry Output for n-Bit Cascading Synchronous Counting Synchronously Programmabledescription/ordering informationThese synchronous, presettable counters feature
an internal carry look-ahead for application in
high-speed counting designs. The ’HC163
devices are 4-bit binary counters. Synchronous
operation is provided by having all flip-flops
clocked simultaneously so that the outputs
change coincident with each other when
instructed by the count-enable (ENP , ENT) inputs
and internal gating. This mode of operation
eliminates the output counting spikes normally
associated with synchronous (ripple-clock)
counters. A buffered clock (CLK) input triggers the
four flip-flops on the rising (positive-going) edge of
the clock waveform.
