You should use a shift register with serial input, parallel output
and reset. The reset signal should be controlled by the output of the
last wanted stage (you can daisy chain those registers to any lenght
you'd like) and you would feed the input with a constant "1". With
every clock pulse, another output will go from "0" to "1", while the
other outputs will remain at their respective states.

74xx96   (xx=none,LS,...)
74xx164  (xx=none,ALS,F,HC,HCT,LS,LV,...)
74xx194  (xx=none,LS,HC,...)
74xx195  (xx=none,LS,...)
74xx395  (xx=none,LS,...)
74xx595  (xx=none,ALS,F,HC,HCT,LS,LV,...)

rt> Hi LIST,
rt> Any help or info for a decade counter IC like the 4017
rt> but with different output.Instead of 1 output is high
rt> and all other output is low, what I need is that when
rt> one output goes high, the previous output remains high
rt> until all output is high then reset back to low.
rt> I tried the 4017 and add some diodes to drive the

rt> Is there an IC that function like this?

rt> Thanks and regards to all.
