Notes: 1. ICC1 depends on output loading and cycle rates. Specified values are obtained with the output

open. In addition to this, ICC1 is measured on condition that addresses are changed only one

time during tCK(MIN.).

2. ICC4 depends on output loading and cycle rates. Specified values are obtained with the output

open. In addition to this, ICC4 is measured on condition that addresses are changed only one

time during tCK(MIN.).

3. ICC5 is measured on condition that addresses are changed only one time during tCK(MIN.).

4. For LVTTL compatible, VG36648041.
