1. Parameter guaranteed by design. t_OSLH = |t_PLHm − t_PLHn|, t_OSHL = |t_PHLm − t_PHLn|.
2. C_PD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load.
Average operating current can be obtained by the equation: I_CC(OPR) = C_PD  V_CC  f_in + I_CC / 8 (per bit). C_PD is used to determine the no−load
dynamic power consumption; P_D = C_PD  V_CC2  f_in + I_CC  V_CC.
