5 / 9 page 5 www.fairchildsemi.com AC Electrical Characteristics Note 9: For CL = 50 pF, add approximately 300 ps to the AC maximum specification. Note 10: 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).
