PURPOSE:To prevent noise from being generated by inhibiting the change of all other outputs at the time of one output is kept in the transient state. CONSTITUTION:When an input from the 2nd input terminal B is logical 1 a transfer gate 3 is nonconductive, a transfer gate 4 is conductive, a latch circuit 1 is latched, and when a signal from the input terminal B is logical 0 conversely, the transfer gate 3 is conductive, the transfer gate 4 is nonconductive and the latch circuit 1 is in the signal passing state. When the 1st output terminal 0 is in the transient state, on output transient state detection signal is outputted from an exclusive OR circuit 7 to the 2nd output terminal C. When 2-stage of output control circuits are provided, the output terminal C of the 1st stage output control circuit and the input terminal B of the 2nd stage output control circuit are connected. |
