• Logic level — In digital circuits, a logic level is one of a finite number of states that a signal can have. Logic levels are usually represented by the voltage difference between the signal and ground (or some other common reference point), although other… …   Wikipedia

• Logic family — In computer engineering, a logic family may refer to one of two related concepts. A logic family of monolithic digital integrated circuit devices is a group of electronic logic gates constructed using one of several different designs, usually… …   Wikipedia

• Logic gate — A logic gate is an idealized or physical device implementing a Boolean function, that is, it performs a logical operation on one or more logic inputs and produces a single logic output. Depending on the context, the term may refer to an ideal… …   Wikipedia

• Diode logic — (DL) or diode resistor logic constructs Boolean logic gates from diodes acting as electrically operated switches. While diode logic has the advantage of simplicity, the lack of an amplifying stage in each gate limits its application. Not all… …   Wikipedia

• Diode–transistor logic — DTL redirects here. For other uses, see DTL (disambiguation). Diode–transistor logic (DTL) is a class of digital circuits that is the direct ancestor of transistor–transistor logic. It is called so because the logic gating function (e.g., AND) is …   Wikipedia

• Transistor–transistor logic — (TTL) is a class of digital circuits built from bipolar junction transistors (BJT), and resistors. It is called transistor–transistor logic because both the logic gating function (e.g., AND) and the amplifying function are performed by… …   Wikipedia

• Low-voltage differential signaling — Low voltage differential signaling, or LVDS, is an electrical signaling system that can run at very high speeds over inexpensive twisted pair copper cables. It was introduced in 1994, and has since become very popular in computers, where it forms …   Wikipedia

• Integrated injection logic — (IIL, I2L, or I2L) is a class of digital circuits built with multiple collector bipolar junction transistors (BJT). 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)… …   Wikipedia

• Resistor–transistor logic — (RTL) is a class of digital circuits built using resistors as the input network and bipolar junction transistors (BJTs) as switching devices. RTL is the earliest class of transistorized digital logic circuit used; other classes include… …   Wikipedia

• Programmable logic controller — A programmable logic controller (PLC) or programmable controller is a digital computer used for automation of industrial processes, such as control of machinery on factory assembly lines. PLCs are used in many different industries and machines… …   Wikipedia
