5474/DM5474/DM7474  
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 informa-  
tion on the D input is accepted by the flip-flops on the posi-  
tive 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 the data 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.
