SEMICONDUCTOR TECHNICAL DATA

High–Performance Silicon–Gate CMOS

N SUFFIX

PLASTIC PACKAGE

CASE 648–08

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.

D SUFFIX

SOIC PACKAGE

CASE 751B–05

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.
