1. Timing measurement reference level is 1.5V for -45 and -55 devices. 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.
Timing measurement reference levels for all other speed grades are V
