(1)

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)

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

(3)

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

(4)

(5)

Input current flows thorough parasitic diode to ground and will turn on parasitic transistors that will increase ICC and may cause output

to be incorrect. Normal operation resumes when input current is removed.
