Notes:
1.
Timing measurement reference level is 1.5V for -45 and -55 devices. Input AC drive levels are V
IL
= 0.0V and V
IH
= 3.0V.
Timing measurement 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.
OE may be delayed up to t

- t
OE
after the falling edge of CE without impact on t
CE
.
OE may be delayed up to t
ACC

This parameter is only sampled and is not 100% tested.
Output float is defined as the point when data is no longer driven.
