(tosLH = |tpLHm − tpLHn|, tosHL = |tpHLm − tpHLn|) Dynamic Switching Characteristics (Ta = 25°C, input: tr = tf = 2.5 ns, CL = 50 pF, RL = 500 Ω) Characteristics Symbol Test Condition VCC (V) Typ. Unit Quiet output maximum dynamic VOL VOLP VIH = 3.3 V, VIL = 0 V 3.3 0.8 V Quiet output minimum dynamic VOL |VOLV| VIH = 3.3 V, VIL = 0 V 3.3 0.8 V Capacitive Characteristics (Ta = 25°C) Characteristics Symbol Test Condition VCC (V) Typ. Unit Input capacitance CIN ⎯ 3.3 7 pF Output capacitance COUT ⎯ 3.3 8 pF Power dissipation capacitance CPD fIN = 10 MHz (Note) 3.3 25 pF Note: 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/8 (per bit) |
