(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. Production
Processing Does Not Necessarily Include Testing of All Parameters.
(2)
All voltage values, except differential voltages, are with respect to network ground.
(3)
Differential voltages are at IN+ with respect to IN–.
(4)
Input current flows thorough parasitic diode to ground and turns on parasitic transistors that increases ICC and may cause output to be
incorrect. Normal operation resumes when input current is removed.
(5)
Short circuits from outputs to VCC can cause excessive heating and eventual destruction.
