1. Stresses greater than those listed under ABSOLUTE MAXIMUM

RATINGS may cause permanent damage to the device. This is a stress

rating only and functional operation of the device at these or any other

conditions above those indicated in the operational sections of this

specification is not implied.

Exposure to absolute maximum rating

conditions for extended periods may affect reliability.

2. VDD terminals only.

3. Input, Output,and I/O terminals; 3.6V maximum.

1. All values are maximum guaranteed values.

2. Input low and high voltage levels are 0.2V and VDD-0.2V respectively for all tests.

3. fMAX = 1/tRC (all address inputs are cycling at fMAX).

4. f = 0 means no address input lines are changing .

5. Typical conditions are VDD = 2.0V and specified temperature.
