Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings

only, which do not imply functional operation of the device at these or any other conditions beyond those indicated under Recommended

Operating Conditions. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

This pin is internally pulled high and clamped at 8 V (typical). The absolute maximum and operating maximum rating specifies the input

level allowed for an external voltage source applied to this pin without triggering the internal clamp with margin.

(3)

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

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

using: PD= (TJ – TA) / RθJA. Exceeding the maximum allowable power dissipation will lead to excessive die temperature.

High junction temperatures degrade operating lifetimes. Operating lifetime is de-rated for junction temperatures greater than 125°C.
