Notes:

1. Timing measurement references are 0.8V and 2.0V. Input AC drive levels are 0.45V and 2.4V, unless otherwise specified.

2. OE/VPP may be delayed up to tCE - tOE after the falling edge of CE without impact on tCE.

3. OE/VPP may be delayed up to tACC - tOE after the address is valid without impact on tACC.

4. This parameter is only sampled and is not 100% tested.

5. Output float is defined as the point when data is no longer driven.
