(TOP VIEW)  
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 PRE and CLR are inactive  
(high), data at the J and K inputs meeting the  
setup-time requirements is transferred to the  
outputs on the negative-going edge of the clock  
pulse (CLK). Clock triggering occurs at a voltage  
level and is not 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.

The output levels in this configuration may not meet the  
minimum levels for V . Furthermore, this configuration is  
nonstable; that is, it does not persist when either PRE or  
CLR returns to its inactive (high) level.
