Abstract
A logic flip flop arrangement wherein each of the two outputs of the flip flop has an output gate associated therewith, wherein an input of each of the output gates is connected to an output of a driving gate, and wherein at least one of the output gates has an output thereof combined with an output of that one of the driving gates which is associated with the other output gate to provide a logic function.
Claims8
An integrated injection logic flip flop arrangement comprising
- a. first and second input gates each having first and second independent outputs;
- b. first and second cross-coupled gates each having first and second independent outputs;
- c. means for cross-coupling said first and second cross-coupled gates wherein an input of said first cross-coupled gate is coupled to said first independent output of said second cross-coupled gate, and an input of said second cross-coupled gate is coupled to said first independent output of said first cross-coupled gate;
- d. means for connecting said first independent output of said first input gate to said input of said first cross-coupled gate;
- e. means for connecting said first independent output of said second input gate to said input of said second cross-coupled gate;
- f. first combining means for combining said second independent output of said first input gate with said second independent output of said second cross-coupled gate;
- and
- g. second combining means for combining said second independent output of said second input gate with said second independent output of said first cross-coupled gate, thus providing two alternative outputs for the flip flop.
