(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 and VCC specified for the measurement of IOS) are with respect to the network GND.

(3)

Differential voltages are at IN+ with respect to IN

−.

(4)

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

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

(5)

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

(6)

The package thermal impedance is calculated in accordance with JESD 51-5.
