ABSTRACT:
A output buffer circuit incorporates an output controller and voltage controller between a first and a second voltage potential to buffer the output of data produced by a semiconductor device. The output controller provides switching control signals to transistors in the voltage controller in order to prevent the first potential from being effected by the potential at the output of the output buffer.
