Four Bit Universal Shift
Register
The MC10141 is a four–bit universal shift register which performs
shift left, or shift right, serial/parallel in, and serial/parallel out
operations with no external gating. Inputs S1 and S2 control the four
possible operations of the register without external gating of the clock.
The flip–flops shift information on the positive edge of the clock. The
four operations are stop shift, shift left, shift right, and parallel entry of
data. The other six inputs are all data type inputs; four for parallel
entry data, and one for shifting in from the left (DL) and one for
shifting in from the right (DR).
