Absolute Maximum Ratings
(All voltages reference to V
SS
)
Note:
Permanent damage to the device may occur if the Absolute Maximum Ratings are exceeded. Operation should be restricted to Recommended
Operating Conditions. Exposure to conditions exceeding the Absolute Maximum Ratings, for an extended period of time, may affect reliability of
this component.
Recommended Operating Conditions
Notes:
1.
Unless otherwise noted, all performance specifications quoted are evaluated for worst case at both 2.75 V

≤
2.375 V (i.e., 2.5 V I/O)
and 3.6 V

DDQ
≤
3.135 V (i.e., 3.3 V I/O) and quoted at whichever condition is worst case.
This device features input buffers compatible with both 3.3 V and 2.5 V I/O drivers.
Most speed grades and configurations of this device are offered in both Commercial and Industrial Temperature ranges. The part number of
Industrial Temperature Range versions end the character “I”. Unless otherwise noted, all performance specifications quoted are evaluated
for worst case in the temperature range marked on the device.
Input Under/overshoot voltage must be –2 V > Vi < V
DD
+2 V with a pulse width not to exceed 20% tKC.
