* 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.
Notes:
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.
The name “VDD” is the same as VDDCORE
