  • High voltage driving circuit reducing a transient current
    Patent number: 6043970
    Abstract: The present invention relates to a high voltage driving circuit for preventing an transient current. The high voltage driving circuit including a non-overlap signal generator for generating the first and second non-overlap signals in response to the logic level signal, a satge for generating a first driving signal in response to the logic level signal and the first and second non-overlap signals, a pre-driving circuit which is driven in response to the first non-overlap signal and the first driving signal, and a complementary output circuit for controlling a current flowing toward the output terminal in response to the output signal of the pre-driving circuit and the second non-overlap signal.
