Notes
1. For CL = 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 (tOSHL) or LOW to HIGH (tOSLH).
