Notes:

1. Timing measurement reference level is 1.5V for -45 devices. Input AC drive levels are V

measurement reference levels for all other speed grades are V

V

2. OE/V

3. OE/V

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.
