The spice model for SN74AUC1G240 seems to be incorrect in that it doesn't invert. I have tried the spice model from a similar part (SN74AUP1G240) and that behaves as expected. Please can you provide a fix?
Many thanks.

Hi Dan,
Thanks for bringing this to our attention. It looks like the model was mistakenly created as a buffer.
The fix is very quick and easy in any text editor.
Just find this section:
Then change "AND" to "0" and "NAND" to "1" -- I will look into getting the model updated for our website as well.
Hey Dan,
,Attached is the zip file for the fixed model. I did a quick simple circuit and it was inverting as intended. If you see different results please let me know.
