Notes:
15. T_A is the case temperature.
16. Overshoot: V_IH ≤ +6.0V for t ≤ t_KC /2.
Undershoot:V_IL ≤ –2.0V for t ≤ t_KC /2.
17. Output loading is specified with C_L = 5 pF as in AC Test Loads.
18. I_CC is given with no output current. I_CC increases with greater output loading and faster cycle times.
19. “Device Deselected” means the device is in Power-Down mode as defined in the truth table. “Device Selected” means the device is active.
20. Typical values are measured at 3.3V, 25°C, and 20-ns cycle time.
