Product data sheet Rev. 8 — 26 June 2013 5 of 19 NXP Semiconductors 74LVC244A; 74LVCH244A Octal buffer/line driver; 3-state 6. Functional description [1] H = HIGH voltage level; L = LOW voltage level; X = don’t care; Z = high-impedance OFF-state. 7. Limiting values [1] The minimum input voltage ratings may be exceeded if the input current ratings are observed. [2] The output voltage ratings may be exceeded if the output current ratings are observed. [3] For SO20 packages: above 70 C derate linearly with 8 mW/K. For (T)SSOP20 packages: above 60 C derate linearly with 5.5 mW/K. For DHVQFN20 and DHXQFN20 packages: above 60 C derate linearly with 4.5 mW/K. Table 3. Function table [1] Control Input Output nOE nAn nYn LLL LH H HX Z Table 4. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
