Abstract
Logic circuitry provides predetermined logic outputs in response to logical combinations of inputs. The circuitry includes a plurality of input devices for receiving logic inputs and capable of assuming conduction states in response to the logic levels of said inputs. At least one output device is connected to two or more input devices. Means having predetermined logic levels is provided connected intermediate the input and output devices for controlling the conduction state of the output devices as a function of the input devices and the predetermined logic levels.
