three-state logic
1Three-state logic — In digital electronics three state, tri state, or 3 state logic allows output ports to have a value of logical 0, 1, or Hi Z. A Hi Z output puts the pin in a high impedance state, effectively removing the pin from its influence on the circuit.… …
2Logic 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… …
3Logic 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… …
4Ternary logic — A ternary, three valued or trivalent logic (sometimes abbreviated 3VL) is a term to describe any of several multi valued logic systems in which there are three truth values indicating true , false and some third value. This is contrasted with the …
5Logic analyzer — A logic analyzer is an electronic instrument which displays signals in a digital circuit. A logic analyzer may convert the captured data into timing diagrams, protocol decodes, state machine traces, assembly language, or correlate assembly with… …
