ABSTRACT:
A plurality of conduction control circuits controls conduction of input signals. A logical operation circuit receives output signals from each of the conduction control circuits via a plurality of signal paths, and performs a logical operation on each of the output signals to output a single signal. A signal-level setting circuit sets, when the conduction of the input signals in the conduction control circuits connected to a same signal path is blocked, a signal level of the signal path. A control-signal generating circuit generates a first control signal that controls the conduction control circuits to select only one input signal for conduction, and a second control signal that controls the signal-level setting circuit to set the signal level of the signal path, by performing a logical operation on a same input signal.
