NOTES: 1. ABSOLUTE MAXIMUM RATING specifies the values beyond which the device may be damaged permanently. Exposure to ABSOLUTE MAXIMUM RATING conditions for extended periods may affect reliability. Each condition value is applied with the other values kept within the following operating conditions and function operation under any of these conditions is not implied. 2. All voltages are measured with respect to VSS(AVSS25A or AVSS25D or AVBB25A) unless otherwise specified. 3. 100pF capacitor is discharged through a 1.5k resistor (Human body model)
