Characteristics of CMOS gate

  1. Oct 3, 2015 #1
    1. The problem statement, all variables and given/known data
    1)Determine the min acceptable values for VIH and VOH using VCC = 4.5 V and output current of 20 µA.

    2)Determine the maximum acceptable values for VOL and VIL under the same test conditions.

    3)Compute the noise margins.

    2. Relevant equations
    i=v/R
    3. The attempt at a solution
    I'm not 100% sure how to read the figure, but the min accepted values seem to be VIH min= 3.15V, VIL min=1.35V.

    My question is, what am I suppose to use the current for? I don't really see where to implement it.

    2) Both seem to be 0V

    3) Completing the first two steps first, not sure how to do this yet.

    Should be VIL max = 1.35V
    You cannot see it your attached, but if you seach the full datasheet, you will see that VIL and VIH is guaranteed by a IOH = 20μA and a IOL = 4mA.
    Search the full datasheet.
