Average operating current can be obtained by the equation: ICC (opr) = CPD·VCC·fIN + ICC/4 (per bit) And the total CPD when n pcs.of flip flop operate can be gained by the following equation: CPD (total) = 30 + 14·n Noise Characteristics (input: tr = tf = 3 ns) Test Condition Ta = 25°C Characteristics Symbol VCC (V) Typ.
