74HC114

HD74HC114 Dual J-K Flip-Flops (with Preset, Common Clear and Common Clock) Description This flip-flop is edge sensitive to the clock input and change state on the negative transition of the clock pulse. each flip-flop has independent J, K and preset inputs and Q and Q outputs. Two flip-flops are controlled by a common clear and a common clock. Preset and clear are independent of the clock and accomplished by a low logic level on the corresponding input. Features High Speed Operation: tpd (Clock to Q) = 18 ns typ (CL = 50 pF) High Output Current: Fanout of 10 LSTTL Loads Wide Operating Voltage: VCC = 2 to 6 V Low Input Current: 1 µA max Low Quiescent Supply Current: ICC (static) = 2 µA max (Ta = 25°C) Free Datasheet http://www.datasheet-pdf.com/ HD74HC114 Function Table Inputs Preset L H L H H H H H H H Note: Clear H L L H H H H H H H L H Clock X X X J X X X L L H H X X X K X X X L H L H X X X Output Q H L H* 1 Q L H H*1 No change L H Toggle No change No change No change H L 1. Q and Q will remain HIGH as long as Preset and Clear are Low, but Q and Q are unpredictable, if Preset and Clear go HIGH simultaneously.
