Note 10: Output-to-Output Skew is defined as the absolute value of the difference between the actual propagation delay for any outputs within the same
packaged device. The specifications apply to any outputs switching in the same direction either HIGH-to-LOW (tOSHL), or LOW-to-HIGH (tOSLH), or in oppo-
site directions both HL and LH (tOST). Parameters tOST and tPS guaranteed by design.
