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.

NOTES:
1. All values are maximum guaranteed values.
2. All inputs switch between 0.2V (Low) and VDD - 0.2V (High).
3. Power specifications are preliminary.
4. fMAX = 1/tRC (all address inputs are cycling at fMAX); f = 0 means no address input lines are changing.
