temperature range.
Note 1: Absolute Maximum Ratings are those values beyond which the life
of the device may be impaired.
Note 2: The maximum differential voltage between any two power pins
(V
operating differential is 15V.

Note 3: During operation near the maximum supply voltage limit, care
should be taken to avoid or suppress power supply turn-on and turn-off
transients, power supply ripple or ground noise; any of these conditions
must not cause a supply differential to exceed the absolute maximum
rating.
