ABSTRACT:
A level converter circuit for converting a first logic signal using a lower voltage supply as a base potential into a second logic signal using a higher voltage supply as a base potential. The level converter circuit comprises first and second bipolar transistors, the base potential of the second logic signal being applied to the collectors of the first and second bipolar transistors, the emitter of the first bipolar transistor being connected to the base of the second bipolar transistor, and the emitter of the second bipolar transistor being used for the output terminal of the level converter circuit, and means for turning on the second bipolar transistor or both bipolar transistors in response to the first logic signal applied to the input terminal.
