Notes:
1. For CL = 50pF, add approximately 300ps to the maximum AC 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).
