4 / 16 page 74LVC2G126_6 © NXP B.V. 2007. All rights reserved. Product data sheet Rev. 06 — 7 September 2007 4 of 16 NXP Semiconductors 74LVC2G126 Dual bus buffer/line driver; 3-state 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] When VCC = 0 V (Power-down mode), the output voltage can be 5.5 V in normal operation. [3] For TSSOP8 packages: above 55 °C the value of P tot derates linearly with 2.5 mW/K. For VSSOP8 packages: above 110 °C the value of P tot derates linearly with 8.0 mW/K. For XSON8 and XQFN8 packages: above 45 °C the value of P tot derates linearly with 2.4 mW/K. 9. Recommended operating conditions Table 4. Function table[1] Input Output nOE nA nY HL L HHH LX Z Table 5. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
