DC Electrical Characteristics (Continued)
Note 5: Outputs in disabled or 3-STATE only.
AC Electrical Characteristics
Note 6: Skew is def ined as t he absolute va lue of the differenc e betwee n the ac tu al propa gation d elay for any two s eparate outpu ts of the same d evi ce. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL) or LOW-to-HIGH (t OSLH). Param eter gu ar antee d by design .
