Editing Resistor–transistor logic (section)

== Advantages ==

The primary advantage of RTL technology was that it used a minimum number of transistors. In circuits using discrete components, before integrated circuits, transistors were the most expensive component to produce. Early IC logic production (such as Fairchild's in 1961) used the same approach briefly, but quickly transitioned to higher-performance circuits such as [[diode–transistor logic]] and then [[transistor–transistor logic]] (starting in 1963 at [[Sylvania Electric Products]]), since diodes and transistors were no more expensive than resistors in the IC.<ref>{{cite book | title = Electronics: The Life Story of a Technology | author = David L.
