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).
