Abstract
A driving circuit which can operates stably without being affected by noise or the like is disclosed. The driving circuit comprises first and second field effect transistors connected in series at a first terminal, a capacitor coupled between the gate of the first transistor and the first terminal, a first control circuit responsive to one of binary levels of an input signal for applying electric charges from a potential source capable of conducting the first transistor to the gate of the first transistor, a second control circuit for applying electric charges from the potential source to the gate of the second transistor, and a third control circuit having a first input terminal receiving the input signal and a second terminal coupled to the gate of the first transistor, the third control circuit discharging the charge at the gate of the second transistor when the potential at the gate of the first transistor is such a value that it makes the first transistor conducting and the input signal is at the mentioned one of the binary levels.
