A level shift circuit comprises an inverter connected to a first voltage supply source and supplied with an input pulse. A condenser and a directional switching element are connected in series between the output point of the inverter and one potential point of the first voltage supply source. The input of a first MOS-FET is connected to the output of the inverter while the input of a second MOS-FET is connected to a connection point between the condenser and the directional switching element. The source of the first MOS-FET is connected to a common terminal of first and second voltage supply sources while the source of the second MOS-FET is connected to the other terminal of the second voltage supply source. An output voltage is generated between a common connecting point of the drains of the first and second MOS-FETs and one potential point of the second voltage supply source.
A level shift circuit comprising an inverter, means for supplying a first voltage to said inverter, means for applying an input pulse to said inverter, a condenser, a directional switching element, and first and second MOS-FETs, means connecting an output of said inverter to one terminal of said condenser and to the gate of said first MOS-FET, means connecting a second terminal of said condenser to the gate of said second MOS-FET and through said directional switching element to one terminal of said first voltage supply means, means connecting the source of said first MOS-FET to the other terminal of said first voltage supply means, means connecting the source of said second MOS-FET to a second voltage supply means, and means connecting the drains of both of said MOS-FETs to an output terminal.
