Notes:
1. Shift register speed can be as low as DC as long as Data Set-up and Hold Time meet the spec.
2. AC Characteristics are guaranteed only under V

Notes:
Power-up sequence should be the following:
1. Connect ground.
2. Apply V
DD
.
3. Set all inputs (Data, CLK, Enable, etc.) to a known state.
Power-down sequence should be the reverse of the above.
