TXU0102 Dual-Bit Voltage-Level Translator Texas Instruments TXU0102 Dual-Bit Fixed Direction Voltage-Level Translator features flexible pin configurations. The Ax pins are referenced to the VCCA logic level, the OE pin can be referenced to either VCCA or VCCB logic levels, and Bx pins are referenced to VCCB logic levels. The A port accepts input voltages ranging from 1.1V to 5.5V, while the B port also accepts input voltages from 1.1V to 5.5V. The fixed direction data transmission occurs 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.
