Abstract
PURPOSE:To prevent an once-through current from flowing to an inverter, by providing a potential control means for fixing the potential of the input terminal of the inverter to an earth point or power supply voltage when all of switching means are brought to an OFF-state. CONSTITUTION:When both of try state buffers TSB1, TSB2 are brought to an output high impedance state by control signals CNT1, CNT2, the feedback circuit of an inverter INV is blocked and oscillation can be stopped. Moreover, when both of the control signals CNT1, CNT2 are brought to a low level and the outputs of two try state buffers TSB1, TSB2 are brought to a high impedance state, the output of an NOR gate G1 is changed to a high level. By this mechanism, the output of a try state buffer TSB3 becomes a low level and the input potential of the inverter INV is fixed to 0V. Therefore, the input terminal of the inverter INV becomes a floating state to prevent the flow of an once-through current.
