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|)
2) Parameter guaranteed by design
(*) Voltage range is 3.3V ± 0.3V

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