The important question is what behaviour should be modeled.
If you want make a simple digital inverter, then an A-device with Vhigh,
Vlow, Ref, Trise and Td will fit. This A-device will be simulated very fast.
Vhigh=5 Ref=2.5 Td=5 Trise=5
I recommend to add a 50 Ohm resistor in series to the output. Adding
the built-in input diodes may be also necessary if the input voltage exceeds
LTspice is strictly standard SPICE on a netlist level.
This means you can directly run the examples(.cir) from the NXP-zip-file.
There is no SPICE standard for schematic entry. This means
symbols are different in every SPICE with schematic entry.
I think that you prefer a schematic instead of a pure netlist.
LTspice offers you different possibilities for symbols.
There are symbols you can edit on an instance level
and others you can't. Both types are useful the same in many cases.
It's a tradeoff regarding versatility and fool proof.
In some cases it's necessary to go with one of them.

Let's hope your email address is valid. If not, send it to my address.
It's a schematic example of an LC-oscilator with the 74HC04U
/74HC04 using the NXP-MOSFET models..
Just replace the value 74HC04U with 74HC04 to switch to a 74HC04.
LC-oscillators should be made with the unbuffered 74HC04U!

rabbits/bunnies from school books. Is that true?
