4-bit Bidirectional Universal Shift Register REJ03D0589- 0200 (Previous ADE-205-466) Rev.2.00 Jan 31, 2006 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: parallel (broadside) load, shift right (in the direction QA toware QD); shift left; inhibit clock (do nothing). Synchronous parallel loading is acplished by applying the four bits of data and taking both mode control...
