DM54194 - 4-Bit Bidirectional Universal Shift Registers

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 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.
