Abstract
A first switch receives an input signal. A second switch receives the input signal, in parallel with the first switch. An output potential sensing inverter detects the potential of an output signal derived from a connection point of the first switch and the second switch. Upon receipt of an output of the output potential sensing inverter, an input switch controls whether the input signal is inputted to the second switch or not. When the potential of the output signal exceeds a predetermined threshold voltage, the output potential sensing inverter performs control such that the input switch be turned off.
