TL/F/5307MM54HC112/MM74HC112 Dual J-K Flip-Flops with Preset and ClearJanuary 1988MM54HC112/MM74HC112Dual J-K Flip-Flops with Preset and ClearGeneral DescriptionThese 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 pre-set are independent of the clock and accomplished by a lowlogic level on the corresponding input.The 54HC/74HC logic family is functionally as well as pin-out compatible with the standard 54LS/74LS logic family.All inputs are protected from damage due to static dis-charge by internal diode clamps to VCCand ground.FeaturesYTypical propagation delay:16 nsYWide operating

package:b12 mW/C from 65C to 85C;ceramic J package:b12 mW/C from 100C to 125C.Note 4:For a power supply of 5Vg10%the worst case output voltages(VOH,and VOL)occur for HC at 4.5V.Thus the 4.5V values should be used when designingwith this supply.Worst case VIHand VILoccur at VCCe5.5V and 4.5V respectively.(The VIHvalue at 5.5V is 3.85V.)The worst case leakage current(IIN,ICC,andIOZ)occur for CMOS at the higher voltage and so the 6.0V values should be used.*VILlimits are currently tested at 20%of VCC.The above VILspecification(30%of VCC)will be implemented no later than Q1,CY89.2AC Electrical
