† 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 conditions beyond those indicated 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 network GND.

2. Differential voltages are at IN + with respect to IN −.

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