Abstract
There is provided an output driver for use in a semiconductor device capable of remarkably improving linearity of impedance by reducing or minimizing a change of an impedance for output data caused due to a change of an external power supply. The output driver for outputting internal data of a semiconductor device to the exterior of a chip comprises a first driving section including a driving transistor to maintain an impedance for applied data at a certain level in response to the data; and a second driving section for compensating for linearity of the impedance in response to an operation signal from the driving transistor of the first driving section and providing an output terminal with the data.
