TINA/Spice/CD4081B-MIL: TINA-TI models for simple logic functions

Part Number:CD4081B-MIL

Tool/software:TINA-TI or Spice Models

Hi

I'm trying to run a sim for a modified version of the UCC3895 transient reference design - it's at http://www.ti.com/lit/tsc/slum186

Anyhow, I want to use some simple logic to perform an AND function on some of the signals and an OR function on some others. I haven't been able to find a generic AND or OR function in TINA and I would like to know if these exist and if so where can I get them.

This is only a sim so I'm not worried about which logic family I use and it doesn't have to be super fast but something like the CD4081 would work nicely for the AND function.

Thanks

Colin
