(1)

Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings

only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating

conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.

(2)

All voltage values, except differential voltages, are with respect to the network ground.

(3)

Differential voltages are at IN+ with respect to IN–.

(4)

Short circuits from outputs to VCC can cause excessive heating and eventual destruction.

(5)

Maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any allowable ambient

temperature is PD = (TJ(max) – TA)/θJA. Operating at the absolute maximum TJ of 150°C can impact reliability.

(6)

The package thermal impedance is calculated in accordance with JESD 51-7.
