5 / 8 page 5 www.fairchildsemi.com AC Electrical Characteristics (Note 8) Note 8: For CL= 50 pF, add approximately 300 ps to the AC maximum specification. Note 9: 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). AC Electrical Characteristics Over Load (Note 10) Note 10: This parameter is guaranteed by characterization but not tested.
