ABSTRACT:
A cell for a shift register comprises an input and an output connected to the line with which it is associated, the cell being parallel-connected on this line, and the output of the cell being separated from the rest of this cell by a tristate buffer circuit. This cell is made in such a way that the state of the inputs of the flip-flop circuits of the cell is never floating when these cells are insulated from the inputs of the cell.
