3. Parameter guaranteed by design. tOSLH = |tPLHm -- tPLHn|, tOSHL = |tPHLm -- tPHLn|.
4. CPD 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: ICC(OPR) = CPD ¯ VCC ¯ fin + ICC/4 (per buffer). CPD is used to determine the
no--load dynamic power consumption; PD = CPD ¯ VCC2 ¯ fin + ICC ¯ VCC.
