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 the
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
