DESCRIPTION

The M54/74HC4017 is a high speed CMOS DE­CADE COUNTER/DIVIDER fabricated in silicon
gate C2MOS technology. It has the same high
speed performance of LSTTL combined with true
CMOS low powerconsumption.

The M54/74HC4017 is a 5-stage Johnson counter
with 10decoded outputs.Each of the decoded out­puts is normally low and sequentially goeshigh on
the lowtohigh transitionoftheclockinput.Each out­put stays high for one clock period of the 10 clock
period cycle. The CARRY output goes low to high
afterOUTPUT10goeslow, and canbeusedincon­junction with the CLOCKENABLE to cascadesev­eralstages.

The CLOCKENABLE input disables countingwhen
in the high state. A RESET input is also provided
whichwhen takenhigh setsall thedecodedoutputs
low.
