DeMorgan Equivalents

#1 Post by gleng » 11 Jul 2018, 23:31

I can find no way to make a DeMorgan equivalent for a gate for using active low logic. For example, if I am using a 74LS00 I might want two of the NAND gates represented as "normal" NAND gates and two as OR gates with active low inputs. Every other schematic package I've ever used can do this, but I don't see a way to associate alternative symbols to a component in DipTrace.

Thank you.

As far as I know, DipTrace does not provide a way to select an alternate DeMorgan equivalent for the provided stock components. You will have to create a custom component with the desired shape and set the appropriate pin Type to "Dot" by using the Pin Manager or double-clicking on the desired pin to bring up the Pin Properties dialog window in the Component Editor.
