Note 1: Absolute Maximum Ratings are those values beyond which the life
of a device may be impaired.
Note 2: The maximum differential voltage between any two power pins
(V +, V , VOH and VOL) must not exceed 18V. The maximum recommended
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.
