Product data sheet Rev. 05 — 5 October 2007 7 of 17 NXP Semiconductors 74LVC3G14 Triple inverting Schmitt trigger with 5 V tolerant input 12. Dynamic characteristics [1] Typical values are measured at Tamb =25 °C and VCC = 1.8 V, 2.5 V, 2.7 V, 3.3 V and 5.0 V respectively. [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+ ∑(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; ∑(C L × VCC 2 × f o) = sum of outputs. Table 9. Dynamic characteristics Voltages are referenced to GND (ground = 0 V). For test circuit see Figure 8.
