ABSTRACT:
A selector circuit precisely outputs a signal selected from a plurality of signals. A latch circuit unit generates an internal selection control signal for controlling a selection operation of a selector circuit unit. When the levels of first and second data input signals do not match each other, the selector circuit unit maintains its selected state and does not perform a selecting operation based on the selection signal until the levels of the signals match each other in accordance with the internal selection control signal.
