Notes:
1. For C_L = 50pF add approximatly 300ps to AC maximum specification.
2. 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 or LOW (t_OSHL) or LOW
to HIGH (t_OSLH).
