TJ = –25 to 90°C.

IDD1 and IDD4 depend on the output loading and cycle rates. All measurements are made with the output open and on

condition that the addresses are changed only once during tCK(min.).

The minimum value of tRC (RAS cycle time for Refresh operation) is shown in Table 14: Asynchronous AC Characteristics.

IDD5 is measured on condition that the addresses are changed only once during tCK (min.).
