MM54HC109A/MM74HC109ADual J-K Flip-Flops with Preset and ClearGeneral DescripTIonThese J-K FLIP-FLOPS uTIlize advanced silicon-gate CMOStechnology to achieve the low power consumpTIon and highnoise immunity of standard CMOS integrated circuits, alongwith the ability to drive 10 LS-TTL loads.Each flip flop has independent J, K PRESET, CLEAR andCLOCK inputs and Q and Q outputs. These devices areedge sensiTIve to the clock input and change state on thepositive going transition of the clock pulse. Clear and presetare independent of the clock and accomplished by a lowlogic level on the corresponding input.
