High–Performance Silicon–Gate CMOS

The MC74C4020A is identical in pinout to the standard CMOS

MC14020B. The device inputs are compatible with standard CMOS

outputs; with pullup resistors, they are compatible with LSTTL

outputs.

This device 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 of that of the preceding one. 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

HC4020A for some designs.
