Stresses above the absolute maximum ratings listed in
Table 13: Voltage characteristics
,
Table 14: Current characteristics
and
Table 15: 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 the device’s reliability.
The device’s mission profile (application conditions) is compliant with JEDEC JESD47
Qualification Standard, extended mission profiles are available on demand.
