[2] CPD is used to determine the dynamic power dissipation PD (W). PD =CPD VCC2 fi + (CL VCC2 fo)where: fi = input frequency in MHz; fo = output frequency in MHz CL = output load capacitance in pF; VCC = supply voltage in Volts (C L VCC 2 f o) = sum of outputs ICC supply current VI =VCC or GND; IO =0A; VCC =5.5 V -- 10 - 20 A I CC additional supply current per input; VCC = 4.5 V to 5.5 V; VI = VCC 2.1 V; IO =0A - - 500 - 850 A CI input capacitance - 1.5 - - - pF VT+ positive-going threshold voltage see Figure 7 and Figure 8 VCC = 4.5 V 1.2 1.55 1.9 1.2 1.9 V VCC = 5.5 V 1.4 1.80 2.1 1.4 2.1 V VT negative-going threshold voltage see Figure 7 and Figure 8 VCC = 4.5 V 0.5 0.76 1.2 0.5 1.2 V VCC = 5.5 V 0.6 0.90 1.4 0.6 1.4 V VH hysteresis voltage see Figure 7 and Figure 8 VCC = 4.5 V 0.4 0.80 - 0.4 - V VCC = 5.5 V 0.4 0.90 - 0.4 - V Table 7.
