Note:
1. Stress greater than those listed under “Absolute Maximum Ratings”may cause permanent damage to the device.
2. All voltages are referenced to VSS.
3. These parameters depend on the cycle rate and these values are measured by the cycle rate under the minimum value of
4. These parameters depend on the output loading.Specified values are obtained with the output open.
5. Power-up sequence is described in Note 11.
* CL is CAS# Latency.
