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:  
Serial data for this mode is entered at the shift-right data  
input. When S0 is low and S1 is high, data shifts left syn-  
chronously and new data is entered at the shift-left serial  
input.  
Clocking of the flip-flop is inhibited when both mode control  
inputs are low.

Four operating modes:  
Synchronous parallel loading is accomplished by applying  
the four bits of data and taking both mode control inputs, S0  
and S1, high. The data is 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 inhibit-  
ed.
