APPLICATIONS
POWER SUPPLY SEQUENCING
As indicated under the Absolute Maximum Ratings, the voltage
at any input pin cannot exceed its supply voltage by more than
0.5 V. To ensure compliance with the Absolute Maximum
Ratings, the following power-up and power-down sequencing is
recommended.
During power-up, initial application of nonzero voltages to any
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.
Power ON
Sequence the applied voltages starting with the highest and
proceeding toward the lowest. Apply AVCC and then proceed
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.

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.
