DM74S112  
Dual Negative-Edge-Triggered Master-Slave J-K Flip-Flop  
with Preset, Clear, and Complementary Outputs  
General Description  
This device contains two independent negative-edge-trig-  
gered J-K flip-flops with complementary outputs. The J and  
K data is processed by the flip-flops on the falling edge of  
the clock pulse. The clock triggering occurs at a voltage  
level and is not directly related to the transition time of the  
negative going edge of the clock pulse. Data on the J and  
K inputs can be changed while the clock is HIGH or LOW  
without affecting the outputs 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.

↓ = Negative going edge of pulse.  
Q0 = The output logic level of Q before the indicated input conditions were  
established.  
* = This configuration is nonstable; that is, it will not persist when either the  
preset and/or clear inputs return to its inactive (HIGH) level.  
Toggle = Each output changes to the complement of its previous level on  
each falling edge of the clock pulse.
