Description

Micrologic is Fairchild's family of planar integrated circuits, and its first part was a flip-flop with four transistors and five resistors. The chips shown come from the later Milliwatt Micrologic series of 1963.

Importance

Micrologic applied Hoerni's planar process and Noyce's patent to a product that customers could buy. Its first large customers were military and space computers, such as the Apollo Guidance Computer. The Apollo program used approximately 200,000 Type G circuits, and it was the largest user of integrated circuits through 1965.

Interesting fact

Fairchild made working junction-isolated circuits on September 27, 1960, and announced Micrologic to the public at the IRE Show in March 1961.
