TXU0104 / TXUN0104 is a 4-bit, dual-supply noninverting fixed direction voltage level translation device. Ax pins are referenced to VCCA logic level, OE pin can be referenced to either VCCA or VCCB logic levels, and Bx pins are referenced to VCCB logic levels. The A port is able to accept input voltages ranging from 1.1V to 5.5V, while the B port can also accept input voltages from 1.1V to 5.5V. Fixed direction data transmission can occur from A to B or B to A when OE is set to high in reference to either supply. When OE is set to low, all output pins are in the high-impedance state. The only difference between TXU0104 and TXUN0104 is the OE / OE signal being active high and active low respectively. See for a summary of the operation of the control logic.
