Note:

1. See AC Waveforms for Read Operation.

10. AC Waveforms for Read Operation⁽¹⁾

Notes: 1. Timing measurement reference level is 1.5V for -45. Input AC drive levels are V_IL= 0.0V and V_IH= 3.0V. Timing measure-

ment reference levels for all other speed grades are V_OL= 0.8V and V_OH= 2.0V. Input AC drive levels are V_IL= 0.45V and V_IH

= 2.4V.

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.
