1. An improved pacer output/input circuit of the type having firstand second output electrode connections for coupling to the heart, for producing a biphasic stimulation output pulse from single ended power supply and having an output voltage twice that of said power supply in response to pace input signals including:

  • a first current limiting buffer for selectively sourcing or sinking current from a first output electrode connection in response to a first control signal;

    a second current limiting buffer for selectively sourcing or sinking current from said second output electrode in response to a second control signal; and

    wherein the improvement comprises;

    means for producing a time sequence of the complementary first and second control signals in response to a sequence of pace input pulses.
