I need help setting up the 74LVC1g74 Flipflop parameters for 5V operation.

From the 74LVC1G.lib file I get the following information:

_________________________________________________________________________________________________________

* Delays have been adjusted for Vcc = 1V8/2V7/3V3/5V (LVC) using the test conditions stated in the
* Nexperia data sheets, and generally achieve Tpd errors less than 10%. The actual VCC voltage needs
* to be passed to each device as a parameter, either a fixed value, or a variable by placing:
*
* - VCC={VCC} Speed=1 Tripdt=100p
*
* in the Value field of the symbol, where {VCC} denotes that it is defined somewhere in the schematic.
*
* Temperature effects are currently not modelled.

Do I use Speed=1 for 5V operation?  What do I use for Tripdt value?  What does Tripdt=100p mean?

 

Your help will be much appreciated.  

Thanks, 

Jim
