    • PURPOSE:To obtain a logical circuit having a fast switching speed and small power consumption, by connecting an impedance varying circuit comprising a depletion MOSFET to a logical element to control the impedance. CONSTITUTION:Depletion D type MOSFETs 9, 10 for load and enhancement E type MOSFETs 11, 12 for drive form an FF circuit, and a reset MOSFET13 and a set MOSFET14 are connected in parallel respectively with the FETs 11, 12. D type MOSFETs 5, 6 are connected in series respectively with the FETs 9, 10, a variable voltage VG is applied to the gates and the FETs 5, 6 forms the impedance variable circuit. since any restriction of the circuit other than the voltage VG equal to the power supply voltage VDD or a value of its vicinity and keeping of the required minimum voltage for holding of storage by this circuit through the constitution like this is not given, the switching speed is fast. Thus, the power consumption is reduced by keeping the power supply and ground to a high impdeance state by controlling the impedance varying circuit other than the power consumption at the circuit operation.

    • PURPOSE:To unify a single power source, by supplying the 1st potential from the single power source and generating the 2nd potential through the parallel circuit of a constant voltage element and electrostatic capacitance. CONSTITUTION:The constant current value of a load FET2 of a Schottky diode SDCL is set twice as great as that of a load FET3 and the maximum constant current value of a driving FET1 is set greater than that of the load FET2. Consequently, the mean values of currents supplied to respective terminals are so set that a current flowing to a power source terminal 7 flows to power source terminals 8 and 9 while divided halves. For this purpose, the constant voltage element is connected between the terminals 8 and 9 to make the potential at the terminal 8 higher. Then, the electrostatic capacitance 22 is connected in parallel to absorb variation in transient current due to the logical operation of the FFs, and consequently the potential at the terminal 8 is held constant against fluctuation, short-circuiting for AC the terminals 8 and 9 to each other.

CONSTITUTION:Gates of driving FETs T3 and T6 are connected to a set input terminal S, and gates of driving FETs T1 and T8 are connected to a reset input terminal R.
