DC Characteristics
Section 14: DC Characteristics
Note: Values in this data sheet are design goals and are subject to change based on the results of
device characterization.
Absolute Maximum Ratings
Caution! The absolute maximum ratings in Table 24 indicate levels where permanent damage to the
device can occur, even if these limits are exceeded for only a brief duration. Functional operation is
not guaranteed under these conditions. Operation at absolute maximum conditions for extended
periods can adversely affect long-term reliability of the device.
