PURPOSE: To obtain a semiconductor integrated circuit operating with a low power consumption by constituting a data output part and a data input part to be connected with data lines by a single FET and preventing a through current from flowing while making the load capacitance of data lines small. ;CONSTITUTION: When control signals 113, 114 of a buss TR logic 110 are respective an H and an L, the n type FET 122 of an integrated circuit 120 is turned OFF and the single (p) type FET 124 of the data input part and the data output part is turned ON and a (p) type FET 125 is turned OFF and then an output becomes the H. At this time, FETs 122, 125 are completely turned OFF to make the load capacitance of data lines small and the through current of a DC. current is not allowed to flow through a circuit 120. At the time the signal 114 is the H, the single (n) type FET 122 becoming the data input part and the data output part is turned ON to make the output the L in a like manner and also FETs 123, 124 are turned OFF and then the same result is obtained. Semiconductor integrated circuits such as small-sized semiconductor storage circuit and so forth operating at high speed with a low power consumption are obtained by making an input signal a low amplitude with a constitution having the small number of TRs.;COPYRIGHT: (C)1996,JPO
