Note 4: Output-to-Output Skew is defined as the absolute value of the difference between the actual propagation delay for any outputs within the same packaged
device and output bank. The specifications apply to any outputs switching in the same direction either LOW to HIGH (t_OSLH) or HIGH to LOW (t_OSHL).
Note 5: Time high is measured with outputs at 2.0V or above. Time low is measured with outputs at 0.8V or below. Input waveform characteristics for t_High, t_Low mea-
surement: f = 66.67 MHz, duty cycle = 50%.
