* CL is CAS# Latency.
Note:
1. Stress greater than those listed under "Absolute Maximum Ratings" may cause permanent damage to the device.
2. All voltages are referenced to V
SS
.
3. These parameters depend on the cycle rate and these values are measured by the cycle rate under the minimum
value of t
CK
and t
RC
. Input signals are changed one time during t
CK
.
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.
