5 / 9 page TC74VHCT9273P/FT/FK 2009-07-01 5 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 ― 4.7 8.9 1.0 10.2 Propagation delay time (CK-Q) tpLH tpHL ― 5.0 ± 0.5 50 ― 7.6 14.1 1.0 16.1 ns 15 ― 7.5 14.4 1.0 16.4 Propagation delay time ( CLR -Q) tpHL ― 5.0 ± 0.5 50 ― 10.4 19.6 1.0 22.3 ns 15 110 185 ― 95 ― Maximum clock frequency fmax ― 5.0 ± 0.5 50 70 100 ― 60 ― MHz Output to output skew tosLH tosHL (Note 1) 5.0 ± 0.5 50 ― ― 1.0 ― 1.0 ns Input capacitance CIN ― ― 4 10 ― 10 pF Power dissipation capacitance CPD (Note 2) ― 13 ― ― ― pF Note 1: Parameter guaranteed by design. tosLH = |tpLHm − tpLHn|, tosHL = |tpHLm − tpHLn| Note 2: 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/8 (per bit) And the total CPD when n pcs.of flip flop operate can be gained by the following equation: CPD (total) = 9 + 4·n |
