Can someone tell me how to design a LM 339 comparator in Tina TI and or Tina 8.

All I can get to come up on my sch. is 1/4 of the component.

Thanks

You just put 4 of the same component in the schematic.

It would be much harder to deal with if it was just one rectangle with a bunch of connections to make.

Thanks Sgt I will try that.I guess dont worry about the extra pins that are on it for the other 3 parts of the comparator.I will draw it and run it thru simulation.

If you ever build with one of these chips ground the inputs of the unused comparators. This prevents them from generating unwanted signals and noise.
