74F109 Dual JK Positive Edge-Triggered Flip-Flop
74F109 Dual JK Positive Edge-Triggered Flip-Flop

The F109 consists of two high-speed, completely independent transition clocked JK flip-flops. The clocking operation is independent of rise and fall times of the clock waveform. The JK design allows operation as a D-type flip-flop refer to F74 data sheet by connecting the J and K inputs.

Asynchronous Inputs LOW input to SD sets Q to HIGH level LOW input to CD sets Q to LOW level Clear and Set are independent of clock Simultaneous LOW on CD and SD makes both Q and Q HIGH
