54LS109/DM54LS109A/DM74LS109A  
Dual Positive-Edge-Triggered J-K Flip-Flops  
with Preset, Clear, and Complementary Outputs  
General Description  
This device contains two independent positive-edge-trig-  
gered J-K flip-flops with complementary outputs. The J and  
K data is accepted by the flip-flop on the rising edge of the  
clock pulse. The triggering occurs at a voltage level and is  
not directly related to the transition time of the rising edge of  
the clock. The data on the J and K inputs may be changed  
while the clock is high or low as long as setup and hold  
times are not violated. A low logic level on the preset or  
clear inputs will set or reset the outputs regardless of the  
logic levels of the other inputs.
