Overview
HD74HC194 4-bit Bidirectional Universal Shift Register 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.
The data are loaded into their respectiv...
