(tosLH = |tpLHm − tpLHn|, tosHL = |tpHLm − tpHLn|) Note 2: Parameter guaranteed by design. Note 3: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption. Average operating current can be obtained by the equation: ICC (opr) = CPD・VCC・fIN + ICC/2 (per F/F) Noise Characteristics (Ta = 25°C, input: tr = tf = 3 ns, CL = 50 pF) Characteristics Symbol Test Condition VCC (V) Typ.
