Notes: 1. IDD1 depends on output loading and cycle rates. Specified values are obtained with the output open.

In addition to this, IDD1 is measured on condition that addresses are changed only one time during

tCK (min.).

2. IDD4 depends on output loading and cycle rates. Specified values are obtained with the output open.

In addition to this, IDD4 is measured on condition that addresses are changed only one time during

tCK (min.).

3. IDD5 is measured on condition that addresses are changed only one time during tCK (min.).
