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, limited protection is provided on other pins. Permanent damage
may occur on unconnected units under high-energy electrostatic fields. Keep unused units in supplied conductive carrier or
shunt the terminals together.
