Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 11: Voltage characteristics,

Table 12: Current characteristics, and Table 13: Thermal characteristics may cause

permanent damage to the device. These are stress ratings only and functional operation of

the device at these conditions is not implied. Exposure to maximum rating conditions for

extended periods may affect device reliability. Device mission profile (application conditions)

is compliant with JEDEC JESD47 Qualification Standard, extended mission profiles are

available on demand.
