ABSOLUTE MAXIMUM RATINGS

ELECTRICAL CHARACTERISTICS

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 in the operational sections of the specifications is not implied. Exposure to

absolute maximum rating conditions for extended periods may affect device reliability.

Note 1: The digital control inputs are diode protected; however, permanent damage may occur on unconnected units under high-

energy electrostatic fields. Keep unused units in conductive foam or shunt the terminals together. Discharge the conductive

foam to the destination socket before insertion.
