I want to model the SN74LVC1G06 (it's an open-drain inverter) in MultiSim, specifically the rise and fall time specifications.

The existing inverter model in Multisim just has rising and falling propagation delays, which doesn't help my case. Could anyone suggest how I can model this part in MultiSim?

How about modeling the open-drain inverter as a combination of a (normal) non-inverting buffer driving an n-channel MOSFET?

This basically mimics what's going on within the open drain inverter!
