Dual D-type Flip-Flops (with Preset and Clear)
Description
The flip-flop has independent data, preset, clear, and clock inputs and Q and Q outputs. The logic level
present at thte data input is transferred to the output during the positive going transition to the clock pulse.
Preset and clear are independent of the clock and accomplished by a low level at the appropriate input.
Features
• High Speed Operation: tpd (Clock to Q or Q) = 14 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)

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.
