Note 1: The Absolute Maximum Ratings are those values beyond which the safety of the device cannot be guaranteed. The device should not be operated at these limits. The parametric values defined in the DC and AC Electrical Characteristics tables are not guaranteed at the absolute maximum ratings. The Recommended Operating Conditions will define the conditions for actual device operation.

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 (tOSLH) or HIGH to LOW (tOSHL). Note 5: Time high is measured with outputs 2.0V or above. Time low is measured with outputs 0.8V or below. Input waveform characteristics for tHigh, tLow measurement: = 66.67 MHz, duty cycle = 50%.
