DC Electrical Characteristics (Continued)
Note 10: Outputs disabled or 3-STATE only.
AC Electrical Characteristics
Note 11: Skew is defined as the absolute value of the difference between the actual propagation delay for any two separate outputs of the same device. The
specification applies to any outputs switching in the same direction, either HIGH-to-LOW (tOSHL), or LOW-to-HIGH (tOSLH).
