Abstract

PURPOSE:To prevent an abnormality from being supplied to an output terminal by switching a bit combiner circuit receiving two signals via a delay circuit by an output of a signal interruption detection circuit receiving the signal not through the delay circuit. CONSTITUTION:Input data D1, D3 are given respectively to signal interruption detecting circuits 1, 2 and also to data delay circuits 3, 4. Outputs D2, D4 of the delay circuits 3, 4 are supplied to the bit combiner circuit 6 and either or them is outputted as an output D5 by an output C3 of a switching control circuit 5. When the output D2 is outputted and the detection circuit 1 detects the signal interruption of the signal D1, the control circuit 5 outputs the output D4 from the output terminal C3. Since the delay time of the delay circuits 3, 4 is set larger than the time required the detection of the detecting circuits 1, 2, no error signal is outputted at the switching.
