Note 9: 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 speci-

fication applies to any outputs switching in the same direction, either HIGH to LOW (tOSHL) or LOW to HIGH (tOSLH). Parameter guaranteed by design.
