TXU0101 is a 1-bit, dual-supply noninverting fixed direction voltage level translation device. A pin is referenced to VCCA logic level, OE pin can be referenced to either VCCA or VCCB logic levels, and B pin is referenced to VCCB logic level. 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 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. See Device Functional Modes for a summary of the operation of the control logic.
