6.1 Overview

The TXB0101 device is a 1-bit directionless level-shifting and voltage translator specifically designed for translating logic voltage levels. The A port accepts I/O voltages ranging from 1.2V to 3.6V, while the B port is able to accept I/O voltages from 1.65V to 5.5V. The device is a buffered architecture with edge rate accelerators (one-shots) to improve the overall data rate. This device can only translate push-pull CMOS logic outputs. If for open-drain signal translation, see TI TXS010X products.
