Notes:
18. Overshoot: VIH ≤ +6.0V for t ≤ tKC /2.
Undershoot:VIL ≤ –2.0V for t ≤ tKC /2.
19. Output loading is specified with CL = 5 pF as in AC Test Loads.
20. ICC is given with no output current. ICC increases with greater output loading and faster cycle times.
21. “Device Deselected” means the device is in Power-Down mode as defined in the truth table. “Device Selected” means the device is active.
22. Typical values are measured at 3.3V, 25°C, and 20-ns cycle time.
