device. It is not recommended to remove filtering capacitors to reduce PCB size or cost.

This might cause incorrect operation of the device.

Absolute maximum ratings

Stresses above the absolute maximum ratings listed in Table 21: Voltage characteristics,

Table 22: Current characteristics, and Table 23: Thermal characteristics may cause

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