ABSOLUTE MAXIMUM RATINGS
Absolute maximum ratings are limiting values to be applied
individually, and beyond which the serviceability of the circuit
may be impaired. Functional operability is not necessarily implied.
Exposure to absolute maximum rating conditions for an extended
period may affect device reliability.

1 Typical thermal impedances: 64-lead LQFP, θJA = 54°C/W; 64-lead LFCSP, θJA
= 26.4°C/W with heat slug soldered to ground plane. These measurements
were taken on a 4-layer board in still air, in accordance with EIA/JESD51-7.
EXPLANATION OF TEST LEVELS
I
100% production tested.
II
100% production tested at 25°C and sample tested at
specified temperatures.
III
Sample tested only.
IV
Parameter is guaranteed by design and characterization
testing.
V
Parameter is a typical value only.
VI
100% production tested at 25°C; guaranteed by design and
characterization testing for industrial temperature range;
100% production tested at temperature extremes for
military devices.
