DM74LS112A  
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-flop 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  
falling edge of the clock pulse. Data on the J and K inputs  
may be changed while the clock is HIGH or LOW without  
affecting the outputs as long as the 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.

Toggle = Each output changes to the complement of its previous level on  
each falling edge of the clock pulse.  
Note 1: This configuration is nonstable; that is, it will not persist when  
preset and/or clear inputs return to their inactive (HIGH) level.
