VDD
Logic supply voltage
VPP
High voltage supply
VIH
High-level input voltage
VDD = 10.8V
VDD = 13.2V
VIL
Low-level input voltage
VDD = 10.8V
VDD = 13.2V
fCLK

IOD
Allowable pulse current through output diodes
Note:
Power-up sequence should be the following:
1. Connect ground.
2. Apply VDD.
3. Set all inputs (Data, CLK, Enable, etc.) to a known state.
4. Apply VPP.
5. The VPP should not drop below VDD or float during operation.
Power-down sequence should be the reverse of the above.
