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 DIR, OE 3.3 7 pF Bus input capacitance CI/O An, Bn 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) AC Test Circuit AC Waveform 90% 10% Output (Bn, An) Input (An, Bn) VOL VOH GND 2.7 V 1.5 V tpLH tpHL tr 2.5 ns tf 2.5 ns 1.5 V Figure 2 tpLH, tpHL Open 6.0 V GND Switch Output Measure RL = 500 Ω CL = 50 pF Parameter Switch tpLH, tpHL Open tpLZ, tpZL 6.0 V tpHZ, tpZH GND Figure 1 |
