Abstract: PURPOSE:To make power consumption low and make operations high-speed by connecting a capacitor between the gate of an MOSFET and the control signal input to give a preset voltage and by providing a circuit which becomes high- impedance separately from other circuits. CONSTITUTION:FET10 is caused to be conductive previously by control clock signal b to precharge line 27 to approximate power source voltage VCC, and next, L-level data signal c is input from input signal terminal 12. Then, FETs 10 and 11 becomes a cut-off state, and line 27 holds a high-impedance state in comparison with other circuits. Therefore, when control clock singal a is applied to control input signal terminal 14, the voltage of line 27 rises rapidly through capacitor 25 according to voltate change of signal a, and a voltage of approximate 2VCC is applied to the gate of FET13, thereby improving the use rate of the power source voltage considerably. Since signal a is applied to the gate of FET3 as a signal voltage approximating the power source voltage, FET3 becomes conductive rapidly to charge up capacitor 18 of a capacity load rapidly, thus making operations high- speed.
