Dual Positive-Edge-Triggered D Flip-Flops  
with Preset, Clear, and Complementary Outputs  
General Description  
This device contains two independent positive-edge-trig-  
gered D flip-flops with complementary outputs. The infor-  
mation on the D input is accepted by the flip-flops on the  
positive going edge of the clock pulse. The triggering  
occurs at a voltage level and is not directly related to the  
transition time of the rising edge of the clock. The data on  
the D input may be changed while the clock is LOW or  
HIGH without affecting the outputs as long as setup and  
hold times are not violated. A low logic level on the preset  
or clear inputs will set or reset the outputs regardless of the  
logic levels of the other inputs.
