MM54HC76/MM74HC76 Dual J-K Flip-Flopswith Preset and ClearGeneral Des criptionThese high speed (30 MHz minimum) J-K Flip-Flops utilizeadvanced silicon-gate CMOS technology to achieve, the lowpower consumption and high noise immunity of standardCMOS integrated circuits, along with the ability to drive 10LS-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 thenegative going transition of the clock pulse. Clear and presetare independent of the clock and accomplished by a lowlogic level on the corresponding input.
