ABSTRACT:
A level conversion circuit of the present invention is connected between a first and a second device respectively operable with a first and a second power source voltage different from each other. A first wave shaping element shapes the waveform of a signal output from the output of the first device. A waveform transferring element transfers a signal output from the first wave shaping element to the second device. A level determining element controls the level of a signal to be input to the second device. A second wave shaping element shapes the waveform of a signal having a level determined by the level determining element. With this configuration, the circuit is capable of transferring a waveform from the first device to the second device rapidly and thereby protecting the devices from damage.
