These pulses can couple in unexpected ways between multiple integrated circuit packages, resulting in reduced … See more Transistor–transistor logic (TTL) is a logic family built from bipolar junction transistors. Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second … See more Fundamental TTL gate TTL inputs are the emitters of bipolar transistors. In the case of NAND inputs, the inputs are the emitters of multiple-emitter transistors, functionally equivalent to multiple transistors where the bases and collectors are … See more Like most integrated circuits of the period 1963–1990, commercial TTL devices are usually packaged in dual in-line packages (DIPs), usually with … See more Successive generations of technology produced compatible parts with improved power consumption or switching speed, or both.
