DESCRIPTION
The
HCC4XXXB
(extended temperature range)
and
HCF4XXXB
(intermediate temperature range)
are monolithic integrated circuits, available in 14-
lead dual in-line for
4024B
and 16-lead dual in-line
for
4020B, 4040B
plastic or ceramic package and
plastic micropackage.
PIN CONNECTIONS
4020B
The
HCC/HCF4020B, 4024B,
and
4040B
are ripple-
carry binary counters. All counter stages are master-
slave flip-flops. The state of a counter advances one
count on the negative transition of each input pulse ;
a high level on the RESET line resets the counter to
its all zeros stage. Schmitt trigger action on the input-
pulse line permits unlimited clock rise and fall times.
All inputs and outputs are buffered.
