Notes:

21. Overshoot: VIH(AC) <VDD + 1.5V for t <tTCYC/2; undershoot: VIL(AC) < 0.5V for t <tTCYC/2; power-up: VIH < 2.6V and VDD <2.4V and VDDQ < 1.4V for

t<200 ms.)

22. Capacitance derating applies to capacitance different from the load capacitance shown in part (a) of AC Test Loads. Values in table are associated with the

operating frequencies listed.

23. Test conditions as specified with the output loading as shown in part (a) of AC Test Loads unless otherwise noted.

24. Output loading is specified with CL = 5 pF as in AC Test Loads.

25. At any given temperature and voltage condition, tKQHZ is less than tKQLZ and tOEHZ is less than tOELZ.

26. OE is a “don’t care” when a byte Write enable is sampled LOW.

27. This is a synchronous device. All synchronous inputs must meet specified set-up and hold time, except for “don’t care” as defined in the truth table.
