*Static-sensitive device. Unused devices should be stored in conductive
material. 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 any other conditions
above those indicated in the operational sections of the specifications is not
implied.
ELECTRICAL CHARACTERISTICS: VS = ±5V, TA = +25°C, unless otherwise indicated.
