Product data sheet Rev. 05 — 5 October 2007 6 of 14 NXP Semiconductors 74LVC3G34 Triple buffer [1] All typical values are measured at VCC = 3.3 V and Tamb =25 °C. 11. 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; VOH HIGH-level output voltage VI =VIH or VIL IO = −100 µA; VCC = 1.65 V to 5.5 V VCC − 0.1 - - V IO = −4 mA; VCC = 1.65 V 0.95 - - V IO = −8 mA; VCC = 2.3 V 1.7 - - V IO = −12 mA; VCC = 2.7 V 1.9 - - V IO = −24 mA; VCC = 3.0 V 2.0 - - V IO = −32 mA; VCC = 4.5 V 3.4 - - V VOL LOW-level output voltage VI =VIH or VIL IO = 100 µA; VCC = 1.65 V to 5.5 V - - 0.1 V IO = 4 mA; VCC = 1.65 V - - 0.7 V IO = 8 mA; VCC = 2.3 V - - 0.45 V IO = 12 mA; VCC = 2.7 V - - 0.6 V IO = 24 mA; VCC = 3.0 V - - 0.8 V IO = 32 mA; VCC = 4.5 V - - 0.8 V II input leakage current VI = 5.5 V or GND; VCC = 0 V to 5.5 V - - ±20 µA IOFF power-off leakage current VCC = 0 V; VI or VO = 5.5 V - - ±20 µA ICC supply current VI = 5.5 V or GND; VCC = 1.65 V to 5.5 V; IO =0A -- 40 µA ∆ICC additional supply current per pin; VCC = 2.3 V to 5.5 V; VI =VCC − 0.6 V; IO =0 A - - 5000 µA Table 7.
