Product data sheet Rev. 09 — 18 March 2010 6 of 19 NXP Semiconductors 74LVC16244A; 74LVCH16244A 16-bit buffer/line driver; 5 V input/output tolerant; 3-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] Above 60 °C the value of P tot derates linearly with 5.5 mW/K. [4] Above 70 °C the value of P tot derates linearly with 1.8 mW/K. 8. Recommended operating conditions Table 4. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
