Notes:
9. All voltage referenced to Ground.
10. Output are impedance controlled. IOH = –(VDDQ/2)/(RQ/5) for values of 175Ω <= RQ <= 350Ωs.
11. Output are impedance controlled. IOL = (VDDQ/2)/(RQ/5) for values of 175Ω <= RQ <= 350Ω.
12. Overshoot: VIH(AC) < VDDQ +0.85V (Pulse width less than tCYC/2), Undershoot: VIL(AC) > –1.5V (Pulse width less than tCYC/2).
13. Power-up: Assumes a linear ramp from 0V to VDD(min.) within 200 ms. During this time VIH < VDD and VDDQ < VDD.
14. VREF (Min.) = 0.68V or 0.46VDDQ, whichever is larger, VREF (Max.) = 0.95V or 0.54VDDQ, whichever is smaller.
