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.
NOTES: 1. All voltage values, except differential voltages, are with respect to GND.
2. Differential voltages are at IN+, with respect to IN−.
3. Short circuits from outputs to V
CC
can cause excessive heating and eventual destruction.
4. Maximum power dissipation is a function of T
