  2. Logic family - Wikipedia

    en.wikipedia.org/wiki/Logic_family

    A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually with compatible logic levels and power supply characteristics within a family. Many logic families were produced as individual components, each containing one or a few related basic ...

  3. Transistor–transistor logic - Wikipedia

    en.wikipedia.org/wiki/Transistor–transistor_logic

    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 "transistor"), as opposed to earlier resistor–transistor logic (RTL) and diode–transistor logic (DTL).

  4. List of 7400-series integrated circuits - Wikipedia

    en.wikipedia.org/wiki/List_of_7400-series...

    Input column – a blank cell means a normal input for the logic family type. Output column – a blank cell means a "totem pole" output, also known as a push–pull output, with the ability to drive ten standard inputs of the same logic subfamily (fan-out N O = 10). Outputs with higher output currents are often called drivers or buffers.

  5. Resistor–transistor logic - Wikipedia

    en.wikipedia.org/wiki/Resistor–transistor_logic

    RTL is the earliest class of transistorized digital logic circuit; it was succeeded by diode–transistor logic (DTL) and transistor–transistor logic (TTL). RTL circuits were first constructed with discrete components, but in 1961 it became the first digital logic family to be produced as a monolithic integrated circuit.

  6. Direct-coupled transistor logic - Wikipedia

    en.wikipedia.org/.../Direct-coupled_transistor_logic

    Direct-coupled transistor logic (DCTL) is similar to resistor–transistor logic (RTL), but the input transistor bases are connected directly to the collector outputs without any base resistors. Consequently, DCTL gates have fewer components, are more economical, and are simpler to fabricate onto integrated circuits than RTL gates.

  7. Logic level - Wikipedia

    en.wikipedia.org/wiki/Logic_level

    In digital circuits, a logic level is one of a finite number of states that a digital signal can inhabit. Logic levels are usually represented by the voltage difference between the signal and ground, although other standards exist. The range of voltage levels that represent each state depends on the logic family being used.

  8. Integrated injection logic - Wikipedia

    en.wikipedia.org/wiki/Integrated_injection_logic

    Integrated injection logic (IIL, I 2 L, or I2L) is a class of digital circuits built with multiple collector bipolar junction transistors (BJT). [1] When introduced it had speed comparable to TTL yet was almost as low power as CMOS , making it ideal for use in VLSI (and larger) integrated circuits .
