Abstract
A semiconductor integrated circuit includes first and second field-effect transistors which have on/off states thereof being controlled by an incoming signal varying within a first potential range, third and fourth field-effect transistors which are controlled by the on/off states of the first and second filed-effect transistors, a node from which an output signal varying within a second potential range is output according to the on/off states of the first through fourth field-effect transistors, and a control circuit which controls a substrate-bias potential of the first field-effect transistor in response to the incoming signal.
