ABSOLUTE MAXIMUM RATINGS
Stresses greater than those listed below may cause permanent
damage to the device. These are stress ratings only. Functional
operation of the device at these or any other conditions greater
than those indicated in the operational sections of this specifica-
tion is not implied. Exposure to absolute maximum rating
conditions for extended periods may affect device reliability.

ESD SENSITIVITY
TIMING SPECIFICATIONS
General Notes
Use the exact timing information given. Do not attempt to
derive parameters from the addition or subtraction of others.
While addition or subtraction would yield meaningful results
for an individual device, the values given in this data sheet
reflect statistical variations and worst cases. Consequently,
parameters cannot be added up meaningfully to derive
longer times.
Timing Notes
Switching characteristics specify how the processor changes its
signals. Designers have no control over this timing—circuitry
external to the processor must be designed for compatibility
with these signal characteristics. Switching characteristics tell
what the processor will do in a given circumstance. Switching
characteristics can also be used to ensure that any timing
requirement of a device connected to the processor (such as
memory) is satisfied.
Timing requirements apply to signals that are controlled by cir-
cuitry external to the processor, such as the data input for a read
operation. Timing requirements guarantee that the processor
operates correctly with other devices.
