You are provided with a black box that has ICs of a logic family. The black box has an inscription that gives hints about the logic family present in the black box.

• The IC numbers start with 74
• The gate speed is inversely proportional to the propagation delay
• It has either an Open Collector output, Totem-pole output, or a three-state output.

What is the logic family inside the black box?
