Stresses above the specified parameters may cause permanent damage to the device. This is a stress
rating only and functional operation of the device at any condition above those indicated in the
operation sections of this specification is not implied.
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.
When powering the device, the maximum power supply ramp time should be set at a rate faster than 400 μs. This
speed is important to ensure that the device resets properly. Measure rise time at 10% and 90%.
