Definition of TermsIn this document, some specifications may be designated as Advance or Preliminary. These designations are based on the
more detailed timing information used by the development system and reported in the output files. These terms are defined
as follows:
Advance:
Initial estimates based on simulation and/or extrapolation from other speed grades, devices, or families. Values
are subject to change. Use as estimates, not for production.
Preliminary:
Based on characterization. Further changes are not expected.
Except for pin-to-pin input and output parameters, the AC parameter delay specifications included in this document are
derived from measuring internal test patterns. All specifications are representative of worst-case supply voltage and junction
temperature conditions. The parameters included are common to popular designs and typical applications. All specifications
are subject to change without notice.

Notes:
1.
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress
ratings only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions
is not implied. Exposure to Absolute Maximum Ratings conditions for extended periods of time may affect device reliability.
V
IN
should not exceed V
CCO
by more than 3.6V over extended periods of time (e.g., longer than a day).
Maximum DC overshoot must be limited to either V
+ 0.5V or 10 mA, and undershoot must be limited to
–
0.5V or 10 mA,
whichever is easier to achieve. The Maximum AC conditions are as follows: The device pins may undershoot to
–
2.0V or overshoot
to V
CCO
+ 2.0V, provided this over/undershoot lasts no more than 11 ns with a forcing current no greater than 100 mA.
