Where can I find the PSpice model for the 74HC193 to use with PSpice for TI?
How do we add it to the libraries?
Thanks

Hi Marco,
Unfortunately for some devices such as counters, we do not provide PSPICE models due to them not being able to be simulated correctly.
This is surprising and disappointing when we were using logic simulators in the 90's that could do it.
Can't you have a "logic" section in PSpice where the simulator does not worry so much about the internal electrical model but only the I/O characteristics?
Hi Marco,
Are you looking for an IBIS model instead? Let me look into this and I will get back to you.
No; IBIS describes only the electrical characteristics of the input and output buffers.
SPICE-based simulators model the analog properties of circuits and have problems with digital logic. Some have workaround with built-in logic gates, but there are no counters. You would have to use a logic simulator for that.
If you want to simulate both the counter logic and the analog properties of its I/Os, then you must use two simulators.
