12-Stage Binary Ripple Counter
High-Performance Silicon-Gate CMOS
The MC74C4040A is identical in pinout to the standard CMOS MC14040. The device inputs are patible with standard CMOS outputs; with pullup resistors, they are patible 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...
