(1)

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

which the device is intended to be functional, but do not include specific performance limits. For specified specifications, see Electrical

Characteristics.

(2)

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

Ω resistor into each pin.

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

which the device is intended to be functional, but do not include specific performance limits. For specified specifications, see Electrical

Characteristics.

(2)

The maximum allowable power dissipation is a function of the maximum junction temperature, TJ_MAX, the junction-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 dissipation of 0.66W is determined using TA = 25°C, θJA = 151°C/W, and

TJ_MAX = 125°C. θJA will vary with board size and copper area. The θJA spec is based on a JEDEC standard 4-layer board.
