Part Number: SN74LVC1G126

When I try to run simulation for this part in Pspice. And I get the following result

I change the GMIN and LIMIT, but I still could not get a result. I attach the project, would you please help me?

Thanks!

I modify the model as the following document, the spice could run, but it is automatically paused after finished

Hello,

Can you tell me what you mean by "automatically paused"? Is the simulation failing, or does it work?

Hello

Sorry for the late reply.

When the simulation finished. It is automatically paused.

I need to push the stop button to see the result.

One additional change I would recommend is to comment out or delete the inductor here:

I don't know why the simulator pauses on your simulation -- but I found that clicking the 'pause' icon caused it continue and finish the simulation.

You can additionally comment out any diodes (lines starting with D...), as these will limit the total number of signals allowed -- the device will still function correctly without them, with the exception of current when exceeding the supply or ground voltages.
