1) Skew is defined as the absolute value of the difference between the actual propagation delay for any twooutputs of the same device switching in the
same direction, either HIGH or LOW (tOSLH = |tPLHm - tPLHn|, tOSHL = |tPHLm - tpHLn|)

1) CPD isdefined as the value of the IC’sinternal equivalent capacitance which is calculated fromthe operating current consumption without load. Average
operting current can be obtained by the following equation. ICC(opr) = CPD • VCC • fIN + ICC/16 (per circuit)
