Note 1. Stresses above 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 another conditions above those indicated in the operational section of the specifi-
cation is not implied. Exposure to absolute maximum rating conditions for extended periods
may affect device reliability.
Note 2. Input voltages may exceed the supply voltages provided the input current is limited to ±100µA.
Note 3. Dissipation rating assumes device is mounted with all leads soldered to printed circuit board.
