DESCRIPTION
The
HCC4031B
(extended temperature range) and
HCF4031B
(intermediate temperature range) are
monolithic integrated circuits, available in 16-lead
dual in-line plastic or ceramic package.
The
HCC/HCF4031B
is a static shift register that
contains 64 D-type, master-slave flip-flop stages
and one stage which is a D-type master flip-flop only
(referred to as a 1/2 stage). The logic level present
at the DATA input is transferred into the first stage
and shifted one stage at each positive-going clock
transition. Maximum clock frequencies up to 16
Megahertz (typical) can be obtained. Because fully
static operation is allowed, information can be per-
manently stored with the clock line in either the low
or high state. The
HCC/HCF4031B
has a MODE
CONTROL input that, when in the high state, allows
operation in the recirculating mode. The MODE
CONTROL input can also be used to select between
two separate data sources. Register packages can
be cascaded and the clock lines driven directly for
high-speed operation. Alternatively, a delayed clock
output(CL
D
) is provided that enables cascading reg-
