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
