Performance is guaranteed only under the conditions listed in the specifications table and is
not guaranteed under the full range(s) described by the Absolute Maximum specifications.
Exceeding any of the absolute maximum/minimum specifications may result in permanent
damage to the device and will void the warranty.
CAUTION: A lthough this device is designed to be as robust as
possible, ESD (Electrostatic Discharge) can damage
this device. This device must be protected at all
times from ESD. Static charges may easily produce
potentials of several kilovolts on the human body or
equipment, which can discharge without detection.
Industry-standard ESD precautions must be employed
at all times.
