FACT DATA
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.
140 MHz Typ. Clock
Outputs Source/Sink 24 mA
Operating Voltage Range: 2.0 to 6.0 V
High Noise Immunity
