Product data sheet Rev. 01 — 3 July 2007 4 of 28 NXP Semiconductors 74AVC2T45 Dual-bit, dual-supply voltage level translator/transceiver; 3-state 8. Limiting values [1] The minimum input voltage rating and output voltage ratings may be exceeded if the input and output current ratings are observed. [2] VCCO is the supply voltage associated with the output port. [3] VCCO + 0.5 V should not exceed 4.6 V. [4] For VSSOP8 package: above 110 °C the value of P tot derates linearly with 8 mW/K. For XSON8 package: above 45 °C the value of P tot derates linearly with 2.4 mW/K. 9. Recommended operating conditions [1] VCCO is the supply voltage associated with the output port. Table 5. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
