5 / 8 page TC74ACT174P/F 2012-02-29 5 AC Characteristics (CL = 50 pF, RL = 500 Ω, input: tr = tf = 3 ns) Test Condition Ta = 25°C Ta = −40 to 85°C Characteristics Symbol VCC (V) Min Typ. Max Min Max Unit Propagation delay time (CK-Q) tpLH tpHL ⎯ 5.0 ± 0.5 ⎯ 7.1 10.1 1.0 11.5 ns Propagation delay time ( CLR -Q) tpHL ⎯ 5.0 ± 0.5 ⎯ 7.4 11.8 1.0 13.5 ns Maximum clock frequency fmax ⎯ 5.0 ± 0.5 85 140 ⎯ 85 ⎯ MHz Input capacitance CIN ⎯ ⎯ 5 10 ⎯ 10 pF Power dissipation capacitance CPD (Note) ⎯ ⎯ 32 ⎯ ⎯ ⎯ 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/6 (per F/F) And the total CPD when n pcs of Flip Flop operate can be gained by the following equation. CPD (total) = 20 + 12・n |
