Product data sheet Rev. 5 — 15 December 2011 5 of 15 NXP Semiconductors 74LVCH32245A 32-bit bus transceiver with direction pin; 5 V tolerant; 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] All supply and ground pins connected externally to one voltage source. [4] Above 70 C the value of P tot derates linearly with 1.8 mW/K. 8. Recommended operating conditions Table 3. Function selection[1] Input Output nOE nDIR nAn nBn L L A = B inputs L H inputs B = A HX Z Z Table 4. Limiting values In accordance with the Absolute Maximum Rating System (IEC 60134). Voltages are referenced to GND (ground = 0 V).
