= 32.71°C/W. These measurements were taken on
a 4-layer board in still air, in accordance with EIA/JESD51-1.
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.
EXPLANATION OF TEST LEVELS
Test
Levels
Description
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 characteriza-
tion testing.
V Parameter is a typical value only.
VI 100% production tested at 25°C; guaranteed by de-
sign and characterization testing for industrial tem-
perature range; 100% production tested at tempera-
ture 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 elec-
trostatic discharges. Therefore, proper ESD precautions are recommended to avoid performance degradation
or loss of functionality.
