Electrical characteristics are guaranteed over full junction tepmerature range (0

°C to 70°C). Ambient tepmerature 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.
