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. Electrical and Mechanical Specifications The absolute maximum ratings of the AA116-72LF are provided in Table 2. Electrical specifications are provided in Table 3. The state of the AA116-72LF is determined by the logic provided in Table 4. Typical performance characteristics of the AA116-72LF are illustrated in Figures 3 through 6.
