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 of time may affect device reliability.
2
Typical thermal impedances (64-lead LQFP);
JA
= 54°C/W. 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.
ESD CAUTION
ESD (electrostatic discharge) sensitive device. Electrostatic charges as high as 4000 V readily
accumulate on the human body and test equipment and can discharge without detection. Although this
product features proprietary ESD protection circuitry, permanent damage may occur on devices
subjected to high energy electrostatic discharges. Therefore, proper ESD precautions are recommended
to avoid performance degradation or loss of functionality.
