www.DataSheet4U.com MC74AC4020 14ĆStage Binary Ripple Counter The MC74AC4020 consists of 14 master-slave flip-flops with 12 stages brought out to pins.
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 ou
