2. T he digital control inputs are diode-protected; however,
permanent damage may occur on unconnected inputs from
high energy electrostatic fields. K eep in conductive foam at
all times until ready to use.
3. Use proper antistatic handling procedures.
4. Absolute Maximum Ratings apply to both packaged devices
and DICE. Stresses above those listed under Absolute Maxi-
mum Ratings may cause permanent damage to the device.
