There is no damage to device with only one parameter set at the limit and all other parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device. CAUTION: Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) 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 should be used at all times. The state of the AA103-72/-72LF is determined by the logic Electrical and Mechanical Specifications provided in Table 4. The absolute maximum ratings of the AA103-72/-72LF are provided in Table 2. Electrical specifications are provided in Tables 3. Typical performance characteristics of the AA103-72/-72LF are illustrated in Figures 3 through 5. Skyworks Solutions, Inc.
