* Stresses above the specified parameters could cause permanent damage to the device. This is a stress rating only
and functional operation of the device at any other condition above those indicated in the operation sections of this
specification is not implied.
Note 6-1 When powering this device from laboratory or system power supplies, it is important that the Absolute
Maximum Ratings not be exceeded or device failure can result. Some power supplies exhibit voltage
spikes on their outputs when the AC power is switched on or off. In addition, voltage transients on
the AC power line may appear on the DC output. When this possibility exists, it is suggested that a
clamp circuit be used.
Note 6-2 When internal power FET operation of these pins is enabled, these pins may be simultaneously
shorted to ground or any voltage up to 3.63V indefinitely, without damage to the device as long as
V
DD33
and V
DDA33
are less than 3.63V and T
A
is less than 70°C.
