PURPOSE:To attain sure selection without eliminating a data stored in a dynamic latch circuit by providing an input transistor (TR) of an inverter circuit and a gate TR to the power supply side while clipping a wired coupling line. CONSTITUTION:Suppose that an input data A is selected and input data selection signals X, Y are logical '1' and '0'. In this case, gate TRs of the 1st inverter circuit are all conducted and gate TRs of the 2nd inverter circuit are all nonconductive. Thus, only an input data A is inverted and outputted at an output terminal OUT. In this case, since input TRs Q3, Q4 are placed remotely from the wired coupling line 3, a data B stored in the dynamic latch circuit 1 is not lost.
