Set-up Time to Active Clock Edge

These timings have been obtained in the measurement conditions described in Table 14: Operating and AC Measurement

Conditions and Figure 13: AC Measurement Load Circuit.

A refresh opportunity must be offered every tELEH. A refresh opportunity is possible either if E is High during the rising edge

of K; or if E is High for longer than 15ns.

The Hi-Z timings measure a 100mV transition from either VOH or VOL to VCCQ/2.

The Low-Z timings measure a 100mV transition from the Hi-Z (VCCQ/2) level to either VOH or VOL.
