ABSTRACT:
In a flip-flop type level-shift circuit, a P-channel MOS transistor whose gate and drain are tied together is connected between a higher potential power supply terminal and a gate of an output stage P-channel MOS transistor. The P-channel MOS transistor together with the output stage P-channel MOS transistor constitutes a current-mirror circuit. The level-shift circuit can provide a constant-current output as high level output, thus making it unnecessary to include a high resistance protection resistor, which has hitherto been connected to an output terminal of the level-shift circuit to prevent destruction of the circuit caused by short-circuiting of the output, as well as permitting increase of the intergration density, reduction of the size and cost and improvement of the reliability of the circuit.
