description  
These devices contain two independent J-K  
negative-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 preset and clear are inactive  
(high), dataattheJandKinputsmeetingthesetup  
time requirements are transferred to the outputs  
on the negative-going edge of the clock pulse.  
Clocktriggeringoccursatavoltagelevelandisnot  
directly related to the fall 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 tying J and K high.

This configuration is nonstable; that is, it will not persist  
when either PRE or CLR returns to its inactive (high) level.
