(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)

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

(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.
