Notes:
17.Output are impedance controlled. IOH = –(VDDQ/2)/(RQ/5) for values of 175 <= RQ <= 350s.
18.Output are impedance controlled. IOL = (VDDQ/2)/(RQ/5) for values of 175 <= RQ <= 350.
19.Power-up: Assumes a linear ramp from 0V to VDD(min.) within 200 ms. During this time VIH < VDD and VDDQ < VDD.
20.VREF (Min.) = 0.68V or 0.46VDDQ, whichever is larger, VREF (Max.) = 0.95V or 0.54VDDQ, whichever is smaller.
21.Tested initially and after any design or process change that may affect these parameters.
