Abstract
PURPOSE:To prevent the increase of power consumption by providing an OR circuit, which inputs all control signals in parallel, and a switch part, which turns on or off according to the output of the OR circuit. CONSTITUTION:All the control signals Ca,Cb, ...Cn, which control the output terminals of drivers 1a, 1b, ...1n, connected to a bus 3, so as to be turned into a high impedance state respectively, are inputted to the OR circuit 4, and the switch part 6 which is controlled by the output of the OR circuit 4, and connects between the power source 5 of a prescribed potential and the bus 3, is provided. When the bus 3 comes to the high impedance state, the output of the OR circuit 4 controls immediately the switch part 6, and connects between the bus 3 and the power source 5 of the prescribed potential. Thus, even when the bus 3 is enable, such a situation that L level can not be maintained, or a large current flows so that the power consumption increases, never takes place.
