Note 1

Recirculate and TRI-STATE Operation

Recirculate is used to maintain data in the shift register after

it has been loaded While the shift register is being loaded

Recirculate must be at a logical ‘‘0’’ When the loading is

completed Recirculate should be brought to a logical ‘‘1’’

This disables the data input and feeds the output of the last

shift cell back to the input of the first shift cell for each of the

8 registers

For the output to be in the TRI-STATE mode output-select

should be at the logical ‘‘1’’ level
