Abstract
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.
