AC Waveforms for Read Operation(1)

Notes: 1. Timing measurement reference level is 1.5V for -45 and -55 devices. Input AC drive levels are VIL = 0.0V and VIH = 3.0V.

Timing measurement reference levels for all other speed grades are VOL = 0.8V and VOH = 2.0V. Input AC drive levels are

VIL = 0.45V and VIH = 2.4V.

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

3. OE 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.
