The 74109 is a positive edge-triggered [latex]\operatorname{J}-{\overline{{K}}}[/latex] flip-flop. The logic symbol (Figure 10–49) and input waveforms (Figure 10–50) are given; sketch Q.

Notes: 1. Positive edge triggering. 2. [latex]{\overline{{K}}}[/latex] instead of K; therefore, for a toggle, J = 1, [latex]{\overline{{K}}}[/latex] = 0.
