Abstract

PURPOSE: To obviate a selector at the external part of an integrated circuit device and to easily execute the increase in a system having plural signal processing integrated circuit device by providing a switching circuit to execute the input output control of a signal.
CONSTITUTION: First and second switching circuits 6a and 6b are provided, whether a signal given from the external part to an input pad 7a is transferred to an input part 5a of a signal processing circuit or the signal is outputted to an output pad 8a as it is is switched by a first switching circuit 6a. By a second switching circuit 6b, whether the signal from an output part 5b of a signal processing circuit is outputted to an output pad 7b is outputted to an output pad 7b or the signal given from the external part to an input pad 8b is outputted to the output pad 7b as it is is switched. Thus, when the system with plural signal processing integrated circuit devices is constituted, the selector is made unnecessary at the external part of the integrated circuit device and the increase is facilitated.
