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

section of this specification is not implied. Exposure to absolute

maximum rating conditions for extended periods may affect

device reliability.

ENVIRONMENTAL CONDITIONS

Ambient Temperature Rating

TAMB = TCASE − (PD × θCA)

TCASE = case temperature in °C

PD = power dissipation in W

θCA = thermal resistance (case-to-ambient)

θJA = thermal resistance (junction-to-ambient)

θJC = thermal resistance (junction-to-case)

ESD CAUTION

ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily accumulate on

the human body and test equipment and can discharge without detection. Although this product features

proprietary ESD protection circuitry, permanent damage may occur on devices subjected to high energy

electrostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance

degradation or loss of functionality.
