Product data sheet Rev. 05 — 9 June 2008 9 of 18 NXP Semiconductors 74AHC74; 74AHCT74 Dual D-type flip-flop with set and reset; positive-edge trigger [1] Typical values are measured at nominal supply voltage (VCC = 3.3 V and VCC = 5.0 V). [2] tpd is the same as tPLH and tPHL. [3] CPD is used to determine the dynamic power dissipation (PD in µW). PD =CPD × VCC2 × fi × N+ Σ(CL × VCC2 × fo) where: fi = input frequency in MHz; fo = output frequency in MHz; CL = output load capacitance in pF; VCC = supply voltage in V; N = number of inputs switching; Σ(C L × VCC 2 × f o) = sum of the outputs. CPD power dissipation capacitance fi = 1 MHz; VI = GND to VCC [3] -12- - - - - pF 74AHCT74; VCC = 4.5 V to 5.5 V tpd propagation delay nCP to nQ, nQ; see Figure 7 [2] CL = 15 pF - 3.3 7.8 1.0 9.0 1.0 10.0 ns CL = 50 pF - 4.8 8.8 1.0 10.0 1.0 11.0 ns nSD, nRD to nQ, nQ; see Figure 7 CL = 15 pF - 3.7 10.4 1.0 12.0 1.0 13.0 ns CL = 50 pF - 5.3 11.4 1.0 13.0 1.0 14.5 ns fmax maximum frequency see Figure 7 CL = 15 pF 100 160 - 80 - 80 - MHz CL = 50 pF 80 140 - 65 - 65 - MHz tW pulse width CP HIGH or LOW; nSD, nRD LOW; see Figure 7 and 8 5.0 - - 5.0 - 5.0 - ns tsu set-up time nD to nCP; see Figure 7 5.0 - - 5.0 - 5.0 - ns th hold time nD to nCP; see Figure 7 0- - 0 - 0 - ns trec recovery time nRD to nCP; see Figure 8 3.5 - - 3.5 - 3.5 - ns CPD power dissipation capacitance fi = 1 MHz; VI = GND to VCC [3] -16- - - - - pF Table 7.
