Abstract
A novel output stage is disclosed which includes first and second output transistors for providing complementary output signals at inverting and noninverting output terminals in response to receipt of an input signal, wherein the output stage includes a single source of current and a pair of current steering transistors which are controlled by circuit means coupled between the input terminal and the control terminals of the current steering transistors to turn on the one of the current steering transistors which is coupled to the one of the inverting and noninverting output terminals which is undergoing a high voltage to low voltage transition and to turn off the other of the current steering transistors in response to the change of state of the input signal received at an input terminal.
