1. Stresses greater than those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.
2. All voltages are referenced to V
3. These parameters depend on the cycle rate and these values are measured by the cycle rate under the minimum value of t
4. These parameters depend on the output loading. Specified values are obtained with the outputs open.
5. Assume minimum column address update cycle t
