In such logic families, OR is the more complicated operation; it may use a NOR followed by a NOT.

Input, output, a B, a NOR B, the, nOR gate is a digital logic gate that implements logical NOR - it behaves according to the truth table to the right.
For other uses of NOR or Nor, see.
NOR is the result of the negation of the, oR operator.Click on the empty area to close the popup.The diagrams above show the construction of a 2-input NOR gate using nmos logic circuitry.The ansi symbol for the NOR gate is a standard OR gate with an inversion bubble connected.The original Apollo Guidance Computer used 4,100 windows xp home edition registration crack ICs, each one containing only a single 3-input NOR gate.It shares this property with the, nAND gate.This article is about NOR in the sense of an electronic logic gate (e.g.In most, but not all, circuit implementations, the negation comes for freeincluding.In the popular cmos and TTL logic families, NOR gates with up to 8 inputs are available: cmos 4001: Quad 2-input NOR gate 4025: Triple 3-input NOR gate 4002: Dual 4-input NOR gate 4078: Single 8-input NOR gate TTL 7402: Quad 2-input NOR gate 7427.Welcome to the companion website for Sedra/Smiths Microelectronic Circuits, 7th edition.
