DESCRIPTION

The HEF4006B is an 18-stage shift register arranged as

two 4-stage and two 5-stage shift registers with a common

clock input (CP). The two 4-stage shift registers each have

a data input (DA, DB) and a data output (O3A, O3B); the two

5-stage shift registers each have a data input (DC, DD) and

data outputs from the fourth and fifth stages (O3C, O4C,

O3D, O4D).

The registers can be operated in parallel or interconnected

to form a single shift register of up to 18 bits. Data are

shifted into the first register position of each register from

the data inputs (DA to DD) and all the data in each register

are shifted one position to the right on the HIGH to LOW

transition of CP.

5. The moment D1 appears at O depends on the register

length.
