APPLICATION INFORMATION

The MC10H141 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).
