MC74HC4040A
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 compatible with standard CMOS
outputs; with pullup resistors, they are compatible 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 signals are subject
to decoding spikes and may have to be gated with the Clock of the
HC4040A for some designs.
