(1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond those indicated under commended operating conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability.
(2) The Human body model (HBM) is a 100 pF capacitor discharged through a 1.5k resistor into each pin. The testing is done according JEDECs EIA/JESD22-A114.
(3) Charged Device Model
(4) Machine Model (MM) is a 200pF capacitor discharged through a 500 nH inductor with no series resistor into each pin. The testing is done according JEDECs EIA/JESD22-A115.
