Notes:
1. Compatible with both 1.8 V and 1.5 V I/O drivers
2. These are DC test criteria. DC design criteria is VREF ± 50 mV. The AC VIH/VIL levels are defined separately for measuring timing param-
eters.
3. VIL (Min)DC = –0.3 V, VIL(Min)AC = –1.5 V (pulse width ≤ 3 ns).
4. VIH (Max)DC = VDDQ + 0.3 V, VIH(Max)AC = VDDQ + 0.85 V (pulse width ≤ 3 ns).

Notes:
1. The peak to peak AC component superimposed on VREF may not exceed 5% of the DC component of VREF.
2. To guarantee AC characteristics, VIH,VIL, Trise, and Tfall of inputs and clocks must be within 10% of each other.
3. For devices supplied with HSTL I/O input buffers. Compatible with both 1.8 V and 1.5 V I/O drivers.
