DM74LS73A  
Dual Negative-Edge-Triggered Master-Slave  
J-K Flip-Flops with 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. The data on the J  
and K inputs is allowed to change 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 clear  
input will reset the outputs regardless of the levels of the  
other inputs.
