Figure 8. Pin input voltage
9.2 Absolute maximum ratings
Stresses above the absolute maximum ratings listed in Table 16: Voltage characteristics,
Table 17: Current characteristics and Table 18: 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.
