How to simulate LVT BiCMOS PSpice models?
I have previously only massaged Philips/NXP/Nexperia logic models from the HCT and LVC families, but took a stab at the LVT since you specifically requested the 74LVT04 in the question comments.  It's a little more complicated than the other two, so I might have screwed something up in the process.  With that disclaimer...below is the 74LVT04.lib file which simulates a single gate when calling a single instance of 74LVT04.  If a 74LVT1G04 existed it would be more equivalent to that (see 74LVC1G04 to see what I'm talking about).  The &quot;nominal parameters&quot; from nomps.lib were used.  Also note that the package parasitics from lvtpkps.s are not present here.

You can also create a full chip 74LVT04D (SO14) by creating another subcircuit which calls 6 instances of the single gate subcircuit.  Below is an example of this (untested).  I didn't attempt it, but this is where you should manually add the package parasitics if you need that extra accuracy.
.SUBCKT 74LVT04D IN1 OUT1 IN2 OUT2 IN3 OUT3 GND OUT4 IN4 OUT5 IN5 OUT6 IN6 VCC
X1 IN1 OUT1 VCC GND 74LVT04
X2 IN2 OUT2 VCC GND 74LVT04
X3 IN3 OUT3 VCC GND 74LVT04
X4 IN4 OUT4 VCC GND 74LVT04
X5 IN5 OUT5 VCC GND 74LVT04
X6 IN6 OUT6 VCC GND 74LVT04
.ENDS 74LVT04D


I don't use PSpice because all the cool kidz (yes, with a Z) use LTspice.  Therefore, below are some screenshots from LTspice which I took...while wearing my shades of course.  I also included the code for the LTspice symbol (74LVT04.asy file) I used.
