Notes:
13.Overshoot: VIH(AC) < VDDQ +0.85V (Pulse width less than tCYC/2), Undershoot: VIL(AC) > –1.5V (Pulse width less than tCYC/2).
14.Power-up: Assumes a linear ramp from 0V to VDD(min.) within 200 ms. During this time VIH< VDD and VDDQ< VDD.
15.All voltage referenced to Ground.
16.Output are impedance controlled. IOH = –(VDDQ/2)/(RQ/5) for values of 175Ω <= RQ <= 350Ω.
17.Output are impedance controlled. IOL = (VDDQ/2)/(RQ/5) for values of 175Ω <= RQ <= 350Ω.
18.This spec is for all inputs except C and C Clock. For C and C Clock, VIL(Max.) = VREF – 0.2V.
19.VREF (Min.) = 0.68V or 0.46VDDQ, whichever is larger, VREF (Max.) = 0.95V or 0.54VDDQ, whichever is smaller.
