Notes:
*Output will not switch below 12V.
Power-up sequence should be the following:
1. Connect ground.
2. Apply V
DD
.
Power-down sequence should be the reverse of the above.
The V
PP
should not drop below V
DD
during operation.
3.
4.
Set all inputs (Data, CLK, Enable, etc.) to a known state.
Apply V
