Abstract
A semiconductor integrated circuit includes a first transistor of a first conductivity-type having a source connected to a first source line and a drain; a second transistor of a second conductivity-type having a source connected to a second source line and a drain; and a plurality of third transistors of the second conductivity-type connected in series between the drain of the first transistor and the drain of said second transistor, each of said third transistors having a gate for receiving an input signal. The second transistor and at least one and not all of the third transistors have a threshold voltage lower than a threshold voltage of the others of the third transistors.
