ABSTRACT:
The disclosure relates to an STL flip flop circuit composed of a pair of latch circuits, the first latch circuit receiving R and S inputs and the clock signal and floating relative to the other latch circuit. The second latch circuit is referenced to ground and is driven by the output of the floating latch circuit. All components are of the schottky type, the semiconductor devices being schottky clamp transistors and the diodes being either TiW or PtSi type. In accordance with a second embodiment of the invention, a pair of inverter circuits are each coupled to the R and S inputs of the first embodiment, one of the inverters being controlled by an external data source, whereby, the inverters always each provide opposite outputs to the R and S inputs, depending upon the data input. Schottky clamp transistors and two different types of schottky diodes are utilized.
