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 Q A toware QD); shift left; 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.
