description  
2D  
These devices contain two independent positive-  
edge-triggered D-type flip-flops. A low level at the  
preset (PRE) or clear (CLR) inputs sets or resets  
the outputs regardless of the levels of the other  
inputs. When PRE and CLR are inactive (high),  
data at the data (D) input meeting the setup time  
requirements is transferred to the outputs on the  
positive-going edge of the clock pulse. Clock  
triggering occurs at a voltage level and is not  
directly related to the rise time of the clock pulse.  
Following the hold-time interval, data at the  
D input may be changed without affecting the  
levels at the outputs.
