Note 12: For CL

=50pF, add approximately 300ps to the AC maximum specification.

Note 13: 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

Note 14: This parameter is guaranteed by characterization but not tested.

Note 15: SSO = Simultaneous Switching Output. Any output combination of LOW-to-HIGH and/or HIGH-to-LOW transition.
