1. 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−to−LOW (tOSHL) or LOW−to−HIGH (tOSLH); parameter
guaranteed by design.

Average operating current can be obtained by the equation: ICC(OPR) = CPD  VCC  fin + ICC / 4 (per bit). CPD is used to determine the no−load
dynamic power consumption; PD = CPD  VCC2  fin + ICC  VCC.
