ABSTRACT:
A differential RS latch circuit has a series structure wherein a first differential transistor pair, a second differential transistor pair and a third differential transistor pair are connected in three stages, and jointly function as one current switch. A first diode serving as a first level shift element is provided in a first current path between a power source node and a grounding node, and second and third diodes serving as second and third level shift elements are provided in a second current path between the power source node and the grounding node. The number of elements provided in the first current path is equal to that of elements provided in the second current path. As a result, the first and second current paths are equal to each other in response speed to a signal, and thus an hazard is prevented from occurring even at the time of the switching operation between the first and second current paths.
