Absolute maximum ratings

Stresses above the absolute maximum ratings listed in the tables below, 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.
