DESCRIPTION
The 'HC393 contain eight flip-flops and additional gating to implement two individual 4-bit counters in a single package. The 'HC393 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 have parallel outputs from each counter
stage so that any submultiple of the input count frequency is available for system timing signals.
The SN54HC393 is characterized for operation over the full military temperature range of -55°C to 125°C. The SN74HC393 is characterized for operation from -40°C to 85°C.
