These bidirectional shift registers are designed to incorporate virtually all of the

• a system designer may want in a shift register they feature parallel inputs parallel outputs right-shift and left-shift serial inputs operating-modecontrol inputs and a direct overriding clear line The register has four distinct modes of operation namely Parallel (broadside) load Shift right (in the direction QA toward QD) Shift left (in the direction QD toward QA) Inhibit clock (do nothing) Synchronous parallel loading is accomplished by applying the four bits of data and taking both mode contr.
