DM74LS194A 4-Bit Bidirectional Universal Shift Register August 1986 Revised March 2000 DM74LS194A 4-Bit Bidirectional Universal Shift Register General Description This bidirectional shift register is designed to incorporate virtually all of the Features a system designer may want in a shift register; they feature 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...
