(1)

Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is intended to be functional, but do not specific performance limits. For specifications and test conditions, see the

Electrical Characteristics.

(2)

The maximum allowable power dissipation is a function of the maximum junction temperature, TJ_MAX, the junctions-to-ambient thermal

resistance,

θJA, and the ambient temperature, TA. The maximum allowable power dissipation at any ambient temperature is calculated

using: PD_MAX = (TJ_MAX – TA)/θJA. The maximum power dissipations of 2.6W is determined using TA = 25°C, θJA = 38°C/W, and TJ_MAX

= 125°C.

(3)

The human body model is a 100 pF capacitor discharged through a 1.5 k

Ω resistor to each pin.
