5 / 13 page 74LVQ273 5/13 Table 9: Capacitive Characteristics 1) CPD is defined as the value of the IC’s internal equivalent capacitance which is calculated from the operating current consumption without load. (Refer to Test Circuit). Average operating current can be obtained by the following equation. ICC(opr) = CPD x VCC x fIN + ICC/8 (per Flip Flop) Figure 4: Test Circuit CL = 50pF or equivalent (includes jig and probe capacitance) RL = 500Ω or equivalent RT = ZOUT of pulse generator (typically 50Ω) Symbol Parameter Test Condition Value Unit VCC (V) TA = 25°C -40 to 85°C -55 to 125°C Min. Typ. Max. Min. Max. Min. Max. CIN Input Capacitance 3.3 5 pF CPD Power Dissipation Capacitance (note 1) 3.3 fIN = 10MHz 30 pF |
