Hi Galen,

To select a different model using the Model Selector you can use the modelName 
argument of the pin configuration command, i.e.

cct.Receiver = ibs['1']('vo', modelName = 'LVC04K_IN_33')

That's okay, if you're looking for help files for eispice you can try the 
Python 
help command, i.e. help(eispice). I've tried to include some help for each 
object etc., but you may find the source files, which have the help strings 
embedded to be more helpful than using the Python help command.

Charles
