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.
