ABSTRACT:
The described embodiment of the present invention provides an output drive circuit having an input circuit comprising a differentially coupled pair of transistors. The output of the differentially paired transistors is provided to a pair of output driver transistors connected in a Darlington or a common collector-common emitter configuration which provides an output pull up signal to an output pin of the integrated circuit containing the described output driver. The opposite output of the differentially coupled pair is provided to a circuit which provides a pull down pulse to quickly shut off the transistor pair during the high to low transition of the output driver transistor. The use of the output driver transistor driver minimizes the current required by the differential pair and the fast pull down circuit eliminates the speed disadvantage of using a transistor pair output driver.
