1. Skew is defined as the absolute value of the difference between the actual propagation delay for any two
outputs of the same device switching in the same direction, either HIGH or LOW (t_OSLH = | t_PLHm - t_PLHn|,
t_OSHL = | t_PHLm - t_PHLn|)

1. C_PD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the
operating current consumption without load. (Refer to Test Circuit). Average operating current can be
obtained by the following equation. I_CC(opr) = C_PD x V_CC x f_IN + I_CC/16 (per circuit)
