Notes: IDD1, IDD3, IDD4, IDD5 are dependent on output loading and cycle rates. Specified values are obtained with the output
open. IDD is specified as an average current. In IDD1, IDD3, and IDD5 address can be changed maximum once while
RAS =VIL. In IDD4, address can be changed maximum once within one EDO page cycle time, tPC.
