Product data sheet Rev. 5 — 15 December 2011 7 of 15 NXP Semiconductors 74LVCH32245A 32-bit bus transceiver with direction pin; 5 V tolerant; 3-state [1] All typical values are measured at VCC = 3.3 V and Tamb =25 C. [2] The bus hold circuit is switched off when VI >VCC allowing 5.5 V on the input pin. [3] Valid for data inputs only. Control inputs do not have a bus hold circuit. [4] The specified sustaining current at the data inputs holds the input below the specified VI level. [5] The specified overdrive current at the data input forces the data input to the opposite logic input state. 10.
