description/ordering information  
The ’ACT109 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 inputs meeting the setup-time requirements are transferred to  
the outputs on the positive-going edge of the clock (CLK) pulse. Clock triggering occurs at a voltage level and  
isnotdirectlyrelatedtotherisetimeoftheclockpulse. Followingthehold-timeinterval, dataattheJandKinputs  
can be changed without affecting the levels at the outputs. These versatile flip-flops can perform as toggle  
flip-flops by grounding K and tying J high. They also can perform as D-type flip-flops if J and K are tied together.
