Hello Christoph,
There is a library with HC and HCT in our group's directory Files > Lib.
Models: 74HCT.lib
Symbols: 74HCT.zip
Please although take a look to the examples from this folder.
It's best practice to copy the symbols(.asy) you need to the folder of your schematic. Although copy the file 74HCT.lib into this folder. Please be ware that these models are somewhat idealized. This means they may behave better than the real parts especially regarding output drive capability.
?
Best regards,
Helmut
