14-STAGE

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 output signals are subject to decoding spikes

and may have to be gated with the Clock of the MC74AC4020 for some designs.

• 140 MHz Typ. Clock

• Outputs Source/Sink 24 mA

• Operating Voltage Range: 2.0 to 6.0 V

• High Noise Immunity
