MC74AC4040  
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.
