6 / 8 page www.fairchildsemi.com 6 AC Electrical Characteristics (Note 11) Note 11: For CL = 50pF, add approximately 300ps to the AC maximum specification. Note 12: 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).
