DESCRIPTION
The
HCC40104B, HCC40194B,
(extended tem-
perature range) and the
HCC40104B, HCF40194B
(intermediate temperature range) are monolithic in-
tegrated circuits, available in 16-lead dual in-line
plastic or ceramic package and plastic micro pack-
age. The
HCC/HCF 40104B
is a universal shift reg-
ister featuring parallel inputs, parallel outputs, SHIFT
RIGHT and SHIFT LEFT serial inputs, and a high-im-
pedance third output state allowing the device to be
used in bus-organized systems. In the parallel-load
mode (S0 and S1 are high), data is loaded into the
associated flip-flop and appears at the output after
the positive transition of the CLOCK input. During
loading, serial data flow is inhibited. Shift-right and
shift-left are accomplished synchronously on the
positive clock edge with serial data entered at the
SHIFT RIGHT and SHIFT LEFT serial inputs, re-
spectively. Clearing the register is accomplished by
setting both mode controls low and clocking the reg-
ister. When the output enable input is low, all outputs
assume the high impedance state. The
HCC/HCF40194B
is a universal shift register featur-
ing parallel inputs, parallel outputs SHIFT RIGHT and
SHIFT LEFT serial inputs, and a direct overriding
clear input. In the parallel-load mode (S0 and S1 are
high), data is loaded into the associated flip-flop and
