12-STAGE  
BINARY RIPPLE  
COUNTER  
The MC74AC4040 consists of 12 master-slave flip-flops. The output of each  
flip-flop feeds the next and the frequency at each output is half that of the preceding  
one. The state of the counter advances on the negative-going edge of the Clock  
input. Reset is asynchronous and active-high.  
State changes of the Q outputs do not occur simultaneously because of internal  
ripple delays. Therefore, decoded output signals are subject to decoding spikes  
and may have to be gated with the Clock of the MC74AC4040 for some designs.
