Abstract
A circuit for transmitting logic signals across a high voltage barrier has a logic signal buffer with true and complement state differential outputs. A binary flip-flop with set and reset inputs is further provided. A first coupling capacitor is coupled to the true buffer output and to the set input of the binary flip-flop. A second coupling capacitor is coupled to the complement buffer output and to the reset input of the binary flip-flop circuit.
