MC74HC4020A
14-Stage Binary Ripple
Counter
High–Performance Silicon–Gate CMOS
MC14020B. The device inputs are compatible with standard CMOS
outputs; with pullup resistors, they are compatible with LSTTL
outputs.
brought out to pins. The output of each flip–flop feeds the next and the
frequency at each output is half of that of the preceding one. Reset is
asynchronous and active–high.
of internal ripple delays. Therefore, decoded output signals are subject
to decoding spikes and may have to be gated with the Clock of the
HC4020A for some designs.
March, 2000 – Rev. 2
The MC74C4020A is identical in pinout to the standard CMOS
This device consists of 14 master–slave flip–flops with 12 stages
State changes of the Q outputs do not occur simultaneously because
