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.
Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of
Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
