Electrical characteristics are guaranteed over full junction temperature range (0
°C to 70°C). Ambient temperature must be
derated based on power dissipation and package thermal characteristics.

ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed under ABSOLUTE 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 conditions above those indicated in the operational sections
of this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
