[sdiy] demuxing 4017 inputs

[bill bigrig]

Howdy,

 I have 4 outputs from and inverter(just after a
scmitt trigger), and can anyone tell me how these
inputs, all tied together, can be separated and mixed
to a single clock input of a 4017? Diodes seem to
throw capacitance everywhere and the thing just
triggers like a random machine gun. Should i try
resistors on the individual inverter outs? I'm running
the system at 5 volts. Even when I unplug the
inverter, providing no inputs, the thing just runs
like crazy. Are the summing diodes causing a
capacitance thing to the inputs? I just need to know
how to make 4 different signals work together to clock
the 4017 input. No more than 1 line is high at the
same time. I'm at a loss. Thanx
Rig
