4-Bit Bidirectional Universal Shift Registers

General Description

This bidirectional shift register is designed to incorporate

virtually all of the features a system designer may want in a

shift register; it features parallel inputs, parallel outputs,

right-shift and left-shift serial inputs, operating-mode-control

inputs, and a direct overriding clear line. The register has

four distinct modes of operation, namely:

Clocking of the flip-flop is inhibited when both mode control

inputs are low. The mode controls of the DM54194/

DM74194 should be changed only while the clock input is

high.

Features

Parallel (broadside) load

Shift right (in the direction Q toward Q )

Parallel inputs and outputs

Shift left (in the direction Q toward Q )

Four operating modes:

Synchronous parallel load

Right shift

Left shift

Inhibit clock (do nothing)

Synchronous parallel loading is accomplished by applying

the four bits of data and taking both mode control inputs, S0

and S1, high. The data is loaded into the associated flip-

flops and appears at the outputs after the positive transition

of the clock input. During loading, serial data flow is inhibit-

ed.

Do nothing

Positive edge-triggered clocking

Direct overriding clear

Typical clock frequency 36 MHz

Typical power dissipation 195 mW

Shift right is accomplished synchronously with the rising

edge of the clock pulse when S0 is high and S1 is low.

Serial data for this mode is entered at the shift-right data

input. When S0 is low and S1 is high, data shifts left syn-

chronously and new data is entered at the shift-left serial

input.
