description/ordering information
The ’HC393 devices contain eight flip-flops and
additional gating to implement two individual 4-bit
counters in a single package. These devices
comprise two independent 4-bit binary counters,
each having a clear (CLR) and a clock (CLK)
input. N-bit binary counters can be implemented
with each package, providing the capability of
divide by 256. The ’HC393 devices have parallel
outputs from each counter stage so that any
submultiple of the input count frequency is
available for system timing signals.
