4-bit Bidirectional Universal Shift Registers - National Semiconductor

These bidirectional Shift registers DM54S194 DM74S194 are designed to incorpo- rate virtually all of the features a system designer may want in a shift register; they feature parallel inputs, parallel out- puts, 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 control inputs, S0 and S1, high. The data are loaded into the associated flip- flops and appear at the outputs after the positive transition of the Clock input. During loading, serial data flow is inhibited.
