description/ordering information  
This circuit is a positive-edge-triggered D-type  
flip-flop with a direct clear (CLR) input.  
GND  
Information at the data (D) inputs meeting the setup  
time requirements is transferred to the Q outputs on  
the positive-going edge of the clock (CLK) pulse.  
Clock triggering occurs at a particular voltage level and is not related directly to the transition time of the  
positive-going pulse. When CLK is at either the high or low level, the D input has no effect at the output.
