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.
