description  
1K  
These devices contain two independent J-K  
positive-edge-triggered 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 J and K input meeting the  
setup-time requirements are 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 J and K inputs may be changed without  
affecting the levels at the outputs. These versatile  
flip-flops can perform as toggle flip-flops by  
grounding K and trying J high. They also can  
perform as D-type flip-flops if J and K are tied  
together.
