The SN74LXC8T245 is an 8-bit, dual-supply noninverting bidirectional voltage level translation device. Ax pins and control pins (DIR and OE) are referenced to VCCA logic levels, and Bx pins are referenced to VCCB logic levels. The A port is able to accept I/O voltages ranging from 1.1 V to 5.5 V, while the B port can accept I/O voltages from 1.1 V to 5.5 V. A high on DIR allows data transmission from A to B and a low on DIR allows data transmission from B to A when OE is set to low. When OE is set to high, both Ax and Bx pins are in the high-impedance state. See Device Functional Modes for a summary of the operation of the control logic.
