SN7400 how can I donload the simulation part

Hello there,

To download the simulation part, just go to the part page, click at "Simulation Models", and then click at "Download Model".

To import it, you may use the PSpice for TI tool offered by the manufacturer here:

And follow up the .CIR instructions shown at this forum:
