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. VIH(Max)=4.6 for pulse width5ns.VIL(Min)=-1.5Vfor pulse width5ns.
3. These parameters depend on the cycle rate and these values are measured by the cycle rate under the
minimum value of tCK and tRC. Input signals are changed one time during tCK.
4. These parameters depend on the output loading. Specified values are obtained with the output open.
5. Power-up sequence is described in Note 12.
