Hi guys, just found this great program which can simulate electronic diagrams. It called Yenka and it was free for a 15 day trail.

The question I've got is how much voltage can the 4017 decade counter handle. I have simulated a bunch of 555 and 4017 led flasher circuits but the simulator all ways tells me the 4017 pin voltage has been exceeded and can only handle 1v.

 

3 to 18 VDC

Show us your diagram, there may be something else going on.

Not familiar with that simulator, however, other simulators require a VDD=xxV parameter to model the supply voltage dependence of the 4000 series of CMOS logic.

 

It happens to me, I can't do anything with this. Did you solve it?

 

Hola Alberto Leandro Tupone

You've bought the software ???
No.. .
Probably the temporary license period is over.

We could see us your design with the intention of seeking some mistakes ??
you could compress your file ***. YKA with WinZip or WinRAR and upload the compressed file.

 

I suggest you try the LTspice simulator.
It's free from Linear Technology and many on these forums us it.

 

Thanks a lot crutschow. Actually this is pretty weird, it doesn't take any voltage for above of 6v. I'll try the LTspice.
By the way, with this soft can also make a PCB? Thanks a lot!

No, LTspice is just a simulator.
