High–Performance Silicon–Gate CMOS  
The MC74C4040A is identical in pinout to the standard CMOS  
MC14040. The device inputs are compatible with standard CMOS  
outputs; with pullup resistors, they are compatible with LSTTL  
outputs.  
This device consists of 12 master–slave flip–flops. The output of  
each flip–flop feeds the next and the frequency at each output is half of  
that of the preceding one. The state 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  
HC4040A for some designs.
