Product data sheet Rev. 02 — 13 January 2009 3 of 16 NXP Semiconductors 74AHC2G241; 74AHCT2G241 Dual buffer/line driver; 3-state 6.2 Pin description 7. Functional description [1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state. 8. Limiting values [1] The input and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] For TSSOP8 package: above 55 °C the value of Ptot derates linearly with 2.5 mW/K. For VSSOP8 package: above 110 °C the value of Ptot derates linearly with 8 mW/K. For XSON8U package: above 45 °C the value of Ptot derates linearly with 2.4 mW/K. Table 3.
