Note:
21. Overshoot: VIH ≤ +6.0V for t ≤ tKC /2.
Undershoot:VIL ≤ –2.0V for t ≤ tKC /2.
22. MODE pin has an internal pull-up and ZZ pin has an internal pull-down. These two pins exhibit an input leakage current of ±30 µA.
23. AC I/O curves are available upon request.
24. ICC is given with no output current. ICC increases with greater output loading and faster cycle times.
25. “Device Deselected” means the device is in Power-Down mode as defined in the truth table. “Device Selected” means the device is active.
26. Typical values are measured at 3.3V, 25°C, and 8.5-ns cycle time.
