POWER SUPPLY SEQUENCING
As indicated under the Absolute Maximum Ratings, the voltage
at any input pin cannot exceed its supply voltage by more than
Ratings, the following power-up and power-down sequencing is
recommended.
During power-up, initial application of nonzero voltages to any
Failure to comply with the Absolute Maximum Ratings may
result in functional failure or damage to the internal ESD
diodes. Damaged ESD diodes may cause temporary parametric
failures, which may result in image artifacts. Damaged ESD
diodes cannot provide full ESD protection, reducing reliability.
To Ensure Grounded Output Mode at Power-Off
If references are active sources:
of the input pins must be delayed until the supply voltage ramps
up to at least the highest maximum operational input voltage.
During power-down, the voltage at any input pin must reach
zero during a period not exceeding the hold-up time of the
power supply.

with applying the voltages in a decreasing order, for example
VRH, V2, and so on. Apply DVCC last.
Power OFF
Remove voltages starting with the lowest and proceed toward
the highest. Remove DVCC and then proceed with the voltages
in an increasing order, for example V1, V2, VRH, and so on.
Remove AVCC last.
