    摘要: A series circuit of two P-channel transistors and a series circuit of two N-channel transistors are used respectively as a latch circuit which temporarily latches an input signal until the power source fluctuation caused by the change of the output signal is suppressed. The gates of the transistors of the two series-circuits are supplied with the output signal of an output-stage circuit and a delayed output signal obtained by delaying the above output signal so that either one of the two series-circuits can be controlled to be turned on so as to temporarily latch an input signal in a dynamic manner until the power source fluctuation is suppressed. Since the gate signals to the transistors of the two series-circuits are directly supplied without being passed through single-channel type transfer gates, a sufficiently large bias voltages are supplied to the gate of the latch circuits even under the low power source voltage. Thus, the output circuit capable of providing a desired operation characteristic even under the low operation voltage can be realized.

    摘要: The source-drain paths of p-channel first and second MOSFETs are connected in series between a node, to which a high-potential power source voltage is supplied, and a signal output node. The source-drain paths of n-channel third and fourth MOSFETs are connected in series between the signal output node and a node to which a low-potential power source voltage is supplied. A signal from an input node is supplied to the gates of said four MOSFETs in a parallel manner. The source-drain path of an n-channel fifth MOSFET is connected in parallel to the source-drain path of the second MOSFET which is not directly connected to the node of the high-potential power source voltage. The gate of the fifth MOSFET is connected to the node of the high-potential power source voltage. The source-drain path of a p-channel sixth MOSFET is connected in parallel to the source-drain path of the third MOSFET which is not directly connected to the node of the low-potential power source voltage. The gate of the sixth MOSFET is connected to the node of the low-potential power source voltage.

    摘要: Either a power-supply potential or a ground potential is applied to a power-supply node through a switch. When a potential higher than the ground potential is applied to an output terminal while the power-supply node is connected to the ground-potential node, the potential of a back gate of a first PMOS transistor incorporated in an output section increases in accordance with the potential of the output terminal, due to a pn-junction provided between the drain and back gate of the first PMOS transistor. At this time, a second PMOS transistor whose source-drain path is connected between the back gate and gate of the first PMOS transistor is turned on, whereby the potential of the back gate of the first PMOS transistor is transferred to the gate thereof.

    摘要: A protection circuit (1) for input comprises two transistors (11, 12) connected in series between a first voltage supply (V.sub.cc) and a second voltage supply (GND), and an intermediate junction point is used as an input terminal and an output terminal. When a surge voltage is applied to the input terminal, since terminals (51, 53) of the two transistors (11, 12) are connected to predetermined junction points in such a way that the transistors can operate as bipolar transistors or cause punch through phenomenon (without causing breakdown operation of a low response speed to surge voltage), the surge voltage can be absorbed at high speed, thus increasing anti-ESD (electro static discharge) rate. Further, a protection circuit for power supply comprises two transistors (31, 32) connected in parallel to each other between a first voltage supply (V.sub.cc) and a second voltage supply (GND). Similarly, the terminals (65, 68) of the two transistors are connected to predetermined junction points in such a way that when a surge voltage is superimposed upon the supply voltage, at least one of the transistors can operate as a bipolar transistor, without causing breakdown operation.
