Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 67 words
A flip-flop circuit comprising a dynamic flip-flop circuit having set and trigger inputs and a set output, a source of clock pulses to trigger said dynamic flip-flop circuit connected to said trigger input, an input diode connected to said set input for supplying an input thereto, feedback means connected between said set input and said set output for effecting R-S-type flipflop operation of said dynamic flip-flop circuit.
Claim 2
Dependent Claim 67 words
