(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)

This input current exists only when the voltage at any of the inputs is driven negative. The current flows through the collector-base

junction of the input clamping device. In addition to the clamping device action, there is lateral n-p-n parasitic transistor action. This

action is not destructive, and normal output states are reestablished when the input voltage returns to a value more positive than –0.3 V

(5)

(6)

If the output transistors are allowed to saturate, the low-bias dissipation and the on-off characteristics of the outputs keep the dissipation

very small (usually less than 100 mW).

(8)

The package thermal impedance is calculated in accordance with JESD 51 (low-K board).
