12-Stage Binary Ripple
Counter
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.
Features
• 140 MHz Typ. Clock
• Outputs Source/Sink 24 mA
• Operating Voltage Range: 2.0 to 6.0 V
• High Noise Immunity
• These are Pb−Free Devices
