ABSTRACT:
A circuit for providing digital output signals carrying large amounts of currents without generating large transients including apparatus for providing a first current path for providing current at a first rate and a first polarity, apparatus for providing a second current path for providing current at the first rate and the first polarity after a first delay, and apparatus for providing a third current path for providing current of the first polarity at a rate greater than the first rate and sufficient for a load connected thereto after a second delay equal to the first delay whereby the current available at the load has built to a level sufficient to sustain the load prior to the provision of the third current.
