ABSTRACT:
A current switching circuit includes first and second FETs of the same channel type whose drain-source paths are commonly connected at one end and whose gates are connected to receive logic input signals in an inverted relation, and the other end of the drain-source path of the first FET is connected to an external circuit. The current switching circuit further includes a bipolar transistor connected to a commonly connected node between the drain-source paths of the first and second FETs.
