ABSTRACT:
A complementary signal output circuit for supplying an in-phase and an anti-phase output signal in response to an input signal. The falling of the in-phase signal from a high to a low level and the rising of the anti-phase signal from a low to a high level are both controlled in a manner which serves to speed up the output of the anti-phase signal and reduce skew between the complementary signals. This is accomplished by providing a number of inverter means, and transistor means which outputs a low-to-high signal to the anti-phase output in response to the inverted input signal. Additional circuitry responsive to the input signal is used to prevent undesired current from flowing through the transistor and inverter means.
