Abstract
PURPOSE:To prevent the generation of a malfunction by detecting an operation period of an output buffer circuit, and applying a latch automatically to a part of a circuit in a device only in its period. CONSTITUTION:The titled device is provided with a detecting circuit 6 for detecting an operation period of an output buffer circuit 2, and a latching circuit 3 for latching a data signal by an output of this detecting circuit 6 and separating a storage element part 4 and an external circuit. In this state, in the output buffer circuit 2 and the operation detecting circuit 6, operations in each output buffer are detected and they are synthesized in a synthesizing circuit 9 and inputted to the latching circuit 3. In the latching circuit 3, the input buffer circuit 2 and the storage element part 4 are separated in a period in which a malfunction is executed, and also, a correct signal is held. In such a way, it can be prevented that the malfunction of the input buffer circuit 2 is propagated to the whole device.
