4-bit Parallel-Access Shift Register

ADE-205-380 (Z)

1st. Edition

Sep. 2000

Description

This shift register features parallel inputs, parallel outputs, J-K serial inputs, Shift/Load control input, and a

direct overriding clear. This shift register can operate in two modes: Parallel load; Shift from Q₀towards

Q₃.

Parallel loading is accomplished by applying the four bits of data, and taking the PE Input low. The data is

loaded into the associated flip-flops and appears at the outputs after the positive transition of the CP input.

During parallel loading, serial data flow is inhibited. Serial shifting occurs synchronously when the PE

input is high. Serial data for this mode is entered at the J-K inputs. These inputs allow the first stage to

perform as a J-K or toggle flip-flop as shown in the function table.
