ABSTRACT:
An integrated D flip-flop circuit including a plurality of inverter gates produces an output signal having a frequency that is equal to the frequency of an applied alternating input signal divided by a predetermined divide ratio wherein the improvement comprises an additional inverter gate that has an output connected to a predetermined one of the interconnected inverter gates and is responsive to a divide inhibit signal being applied to an input thereof for changing the divide ratio of the D flip-flop circuit.
