*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.
