13.2 Environmental Ratings
The environmental ratings are shown in
13.3 Electrostatic Discharge Specifications
Extreme caution must be exercised to prevent electrostatic discharge (ESD) damage. Proper use of wrist and heel grounding straps
to discharge static electricity is required when handling these devices. Always store unused material in its antistatic packaging.
13.4 Recommended Operating Conditions and DC Characteristics
Caution!
Functional operation is not guaranteed outside of the limits shown in
. Operation outside these limits for extended
periods can adversely affect long-term reliability of the device.
