1. See AC Waveforms for Read Operation.
1. Timing measurement reference level is 1.5V for -45. Input AC drive levels are V
2. OE may be delayed up to t
3. OE may be delayed up to t
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.
ment reference levels for all other speed grades are V
= 2.4V.
