Call it (positive logic) AND or call it (negative logic) OR, or what ever you might want to call it. The only interesting thing is the truth table. And I know how it looks like if you speak of a (positive logic) AND or an (negative logic) OR.

Unfortunately, by convention, gate functionality is almost always (I don't know of any opposite case) expressed based on positive logic. As you will see here, for instance:








There's no one word, that this is no AND gate. So, why shall I call the CD4082 an (negative logic) OR gate, when it's called by the manufacturer an AND gate? I have to call the CD4082 somehow, and, of course, I use the name given by the manufacturer. So, what's wrong when I and Richard and others call this darn thing CD4082 an AND gate, just because it is an AND gate???
