Logic unit cells are disclosed, consisting of an array of high speed logic gates, the outputs of which are wired together and coupled to a low power driver. High speed and switching rates are achieved by using very fast logic gates which have no gain and make use of a wired logic function in order to effect two levels of logic without adding the propagation delay through another logic gate. These arrays of logic gates are coupled to drivers which restore logic levels and provide the necessary power for driving interconnect capacitances while consuming and dissipating a minimum of power in the process. Another logic circuit discloses an array of logic gates as inputs to another logic gate, the individual gates consisting of gallium arsenide components and having drivers built into the output stage of each gate.
