10. AC Waveforms for Read Operation⁽¹⁾

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 may be delayed up to t_CE- t_OEafter the falling edge of CE without impact on t_CE

3. OE may be delayed up to t_ACC- t_OEafter the address is valid without impact on t_ACC

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.
