Product data sheet Rev. 01 — 24 January 2007 4 of 12 NXP Semiconductors 74LVTH322245 3.3 V 32-bit bus transceiver with 30 Ω termination resistors; 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] Stresses beyond those listed may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions beyond indicated under Section 8 “Recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. [2] The performance capability of a high-performance integrated circuit in conjunction with its thermal environment can create junction temperatures which are detrimental to reliability. [3] The input and output negative voltage ratings may be exceeded if the input and output clamp current ratings are observed. 4A[0:7] N5, N6, P5, P6, R5, R6, T6, T5 input or output 4B[0:7] N2, N1, P2, P1, R2, R1, T1, T2 input or output GND B3, B4, D3, D4, E3, E4, G3, G4, K3, K4, M3, M4, N3, N4, R3, R4 ground (0 V) VCC C3, C4, F3, F4, L3, L4, P3, P4 supply voltage Table 2.
