ABSTRACT:
An output buffer circuit according to the present invention has a complementary inverter circuit and a controlling circuit which produces a pair of driving signals for shifting the complementary inverter circuit between two levels, and the controlling circuit has a pull-down transistor and a pull-up transistor both shifted from the off-states to the on-states on the way between the two levels, so that the driving signals slowly swing their voltage levels in an early stage but steeply reaches the two levels, thereby eliminating any overlapping from the driving signals for elimination of undesirable concurrent on-states from the complementary inverter circuit.
