![]() ![]() TTL devices were originally made in ceramic and plastic dual in-line package(s) and in flat-pack form. ![]() Variations of the original TTL circuit design offered higher speed or lower power dissipation to allow design optimization. TTL manufacturers offered a wide range of logic gates, flip-flops, counters, and other circuits. The 7400 series by Texas Instruments became particularly popular. Īfter their introduction in integrated circuit form in 1963 by Sylvania Electric Products, TTL integrated circuits were manufactured by several semiconductor companies. Sometimes TTL-compatible logic levels are not associated directly with TTL integrated circuits, for example, they may be used at the inputs and outputs of electronic instruments. TTL integrated circuits (ICs) were widely used in applications such as computers, industrial controls, test equipment and instrumentation, consumer electronics, and synthesizers. Its name signifies that transistors perform both the logic function (the first "transistor") and the amplifying function (the second "transistor"), as opposed to resistor–transistor logic (RTL) or diode–transistor logic (DTL). 100M Ω(at 500VDC megger between all terminals and case)ħ50VAC 50/60Hz for 1 minute(Between all terminals and case)ġ.5mm amplitude or 300m/s 2 at frequency of 10 to 55Hz(for 1 min.Transistor–transistor logic ( TTL) is a logic family built from bipolar junction transistors. 80mA(disconnection of the load), Line driver output : Max. 1 μs(5VDC : Output resistance 820 Ω), Max.
