data in the 32nd stage is shifted into the first stage
when the LEFT/RIGHT CONTROL is low and from
the 1st stage to the 32nd stage when the
LEFT/RIGHT CONTROL is high.

DESCRIPTION
The
HCC40100B
(extended temperature range)
and
HCF40100B
(intermediate temperature range)
are monolithic integrated circuits, available in 16-
lead dual in-line plastic or ceramic package and
plastic micro package. The
HCC/HCF40100B
is a
32-stage shift register containing 32 D-type master-
slave flip-flops. The data present at the SHIFT-
RIGHT INPUT is transferred into the first register
stage synchronously with the positive CLOCK edge,
provided the LEFT/RIGHT CONTROL is at a low
level, the RECIRCULATE CONTROL is at a high
level, and the CLOCK INHIBIT is low. If the
LEFT/RIGHT CONTROL is at a high level and the
RECIRCULATE CONTROL is also high, data at the
SHIFT-LEFT INPUT is transferred into the 32nd reg-
ister stage synchronously with the positive CLOCK
transition, provided the CLOCK INHIBIT is low. The
state of the LEFT/RIGHT CONTROL, RECIRCU-
LATE CONTROL, and CLOCK INHIBIT should not
be changed when the CLOCK is high. Data is shifted
one stage left or one stage right depending on the
state of the LEFT/RIGHT CONTROL, synchron-
ously with the positive CLOCK edge. Data clocked
into the first or 32nd register states is available at the
SHIFT-LEFT or SHIFT-RIGHT OUTPUT respec-
tively, on the next negative CLOCK transition (see
Data Transfer Table). No shifting occurs on the posi-
tive CLOCK edge if the CLOCK INHIBIT line is at a
high level. With the RECIRCULATE CONTROL low,
