Shift register (CD4094)

Hey,I'm looking for Shift register who known as CD4094

I would like to combine this device in analog circuit . I saw that Pspice can't combine digital devices with analong devices

Am I right? It's verry wierd tp me that I can't simulate a simple circuit with this basic device

The CD4094 shift register is in the "mix_misc.olb" library.  PSpice A/D can simulate circuits containing digital and analog components.

I found it but it worked only with "digclock" and not responded as I wished for rectangular pulses input which generated with "Vpulse" and I wonder If there is an option to do that

My set up had the same results as yours.  It must have something to do with the auto generated A/D interface with Vpulse that causes the problem as I've had other mixed circuits work without any issues.

So I understand that there is a problem to use this device with combined circuits

I would say yes.  I put a CD4011 between Vpulse and the CD4094 clock input and had timing errors which crashed the simulation.
