The input negative voltage and output voltage
ratings may be exceeded if the input and output
current ratings are observed.

Stresses
greater
than
those
listed
under
MAXIMUM RATINGS may cause permanent
damage to the device. This is a stress rating only
and functional operation of the device at these or
any other condi-tions above those indicated in the
operational sec-tions of this specification is not
implied. Exposure to absolute maximum rating
conditions
for
extended
periods
may
affect
reliability.

1. H = HIGH Signal Level,
L = LOW Signal Level
X = Don’t Care or Irrelevant,
Z = High Impedance
