- The first computer (a mechanical analog computer) is believed to have been invented circa 100BC by Archimedes.
- The first digital computer (a mechanical computer) was invented about 1837 by Charles Babbage.
- The first electronic digital computer was invented in 1937 by John Vincent Atanasoff.
- The first integrated circuit (a hybrid device) was invented between 1949 and 1951 independently by Werner Jacobi, Geoffrey W. A. Dummer, and several others; however the first working units had to be built with sockets for special miniaturized vacuum tubes, it was only late in the 1950s that transistors replaced the tubes in these devices.
- The first monolithic integrated circuit was invented in 1958 by Jack Kilby, this germanium device was not very practical to manufacture and never went beyond prototype development.
- The first practical monolithic integrated circuit was invented independently in 1959 by Robert Noyce, this silicon device was rapidly improved on.
- The first transistor (a germanium point contact transistor) was invented in 1947 by John Bardeen and Walter Brattain.
- The first junction transistor (a germanium grown junction transistor) was invented in 1948 by William Shockley.

What is the application of TTL in integrated circuits?
Transistor transistor logic is one type of many different types of bipolar transistor based digital logic circuitry. It is very efficiently implemented in integrated circuit chips, needs only one power supply voltage, and operates at reasonably high speeds. Transistor transistor logic was first developed in the middle 1960s as a modification of the diode transistor logic, then in use in some digital logic integrated circuit chips but dating back to the earliest discrete bipolar transistor logic developed in the late 1950s and derived from vacuum tube point contact diode logic used in many early first generation computers. Transistor transistor logic integrated circuits dominated the computer and electronic digital controller market from the late 1960s until the middle 1980s, when metal oxide semiconductor field effect transistor based microprocessors and microcontrollers began to replace it. By the early 1990s transistor transistor logic and other bipolar transistor based digital logic integrated circuits had been replaced with equivalent complementary metal oxide semiconductor field effect transistor integrated circuits that were both faster and consumed less power (thus running much cooler) or with programmable logic devices of various types. In general transistor transistor logic is now considered obsolete.
