An integrated circuit having a latch circuit with a selection function includes a selection circuit having a plurality of logic circuits each capable of presenting three output states depending on a selection signal supplied thereto, a latch circuit having a bistable circuit composed of first and second logic inverting circuits, and a connection system for supplying an output of the selection circuit to an input of the latch circuit. An output resistance of the second logic inverting circuit is set to be at least ten times as high as an output resistance of any one of the logic circuits which make up the selection circuit.
