Celanese Ateva® A Ethylene Vinyl Acetate Copolymer Molding Resin

A Darlignton pair is two transistors that act as a single transistor providing high current gain. When high logic is fed to the input both the transistors begin to conduct providing a path to ground for the external load that the output is connected. When no base voltage is applied that when is no signal is given to the input pins of the ICthere will be no base current and transistor remains in off state.
