Description
The flip-flop is edge sensitive to the clock input and change state on the negative going transition of the clock pulse.
Each flip-flop has independent, J, K, clock, and clear inputs and Q and Q outputs. Clear is independent of the clock and
accomplished by a low level on the 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)
• Ordering Information
