2. The specified values are obtained with the output open.
3. Input signals are changed once during three clock cycles.
4. Input signals are stable.
5. Active standby current will be higher if Clock Suspend is entered during a Burst Read cycle (add 1mA per DQ).
6. Input signals are changed once during t
