Transistor-Transistor Logic!  Sorry, it came back to me.  Actually, TTL was one of the first digital logic circuits or integrated circuits (ICs).  The transistor allowed the removal of a lot of diodes off a circuit.

  Hee hee, you younglings need an old fart to tell you about TTL.  Except, I am having a senior moment and can't remember what the first "T" means.  The other two letters are Transistor Logic.  

  Transistors came out when I was a kid.  They are these tiny replacements for the vacuum tube that helped put a man on the moon.  :)
