4 / 8 page TC74VHC21F/FT/FK 2012-02-29 4 AC Characteristics (input: tr = tf = 3 ns) Test Condition Ta = 25°C Ta = −40 to 85°C Characteristics Symbol VCC (V) CL (pF) Min Typ. Max Min Max Unit 15 ― 4.8 7.0 1.0 8.5 3.3 ± 0.3 50 ― 7.3 10.5 1.0 12.0 15 ― 3.3 5.0 1.0 6.0 Propagation delay time tpLH tpHL ― 5.0 ± 0.5 50 ― 4.8 7.0 1.0 8.0 ns Input capacitance CIN ― ― 4 10 ― 10 pF Power dissipation capacitance CPD (Note) ― 20 ― ― ― pF Note: CPD is defined as the value of the internal equivalent capacitance which is calculated from the operating current consumption without load. Average operating current can be obtained by the equation: ICC (opr) = CPD·VCC·fIN + ICC/2 (per gate) Input Equivalent Circuit INPUT |
