4-bit Parallel-Access Shift Register

REJ03D0457–0300

Rev.3.00

Jul.15.2005

This 4-bit register features parallel inputs, parallel outputs, J-K serial inputs, shift / load control input, and a direct

overriding clear. All inputs are buffered to lower the input drive requirements. The registers have two modes of

operation:

•

Parallel (broadside) load

Shift (in the direction Q_Atoward Q_D)

Parallel loading is accomplished by applying the four bits of data and taking the shift / load control input low. The data

is loaded into the associated flip-flop and appears at the outputs after the positive transition of the clock input. During

loading, serial data flow is inhibited. Shifting is accomplished synchronously when the shift / load control input is high.

Serial data for this mode is entered at the J-K inputs. These inputs permit the first stage to perform as a J-K, D-, or T-

type flip-flop as shown in the function table.
