DESCRIPTION

The M54/74HC4024 is a high speed CMOS 7­STAGE BINARY COUNTER fabricated in silicon
gate C2MOS technology. It has the same high
speed performance of LSTTL combined with true
CMOS low power consumption. The HC4024is a 7
stage Counter. This devices is incremented on the
falling edge (negative transition) of the input clock,
andall itsoutputsarereset toalowlevelby applying
a logical high on their reset input. All inputs are
equipped with protection circuits against static dis­charge andtransient excess voltage.
