8.1 Overview
The TXS0102-Q1 device is a directionless voltage-level translator specifically designed for translating logic
voltage levels. The A port is able to accept I/O voltages ranging from 1.65 V to 3.6 V, while the B port can accept
I/O voltages from 2.3 V to 5.5 V. The device is a pass gate architecture with edge rate accelerators (one shots)
to improve the overall data rate. 10-kΩ pullup resistors, commonly used in open drain applications, have been
conveniently integrated so that an external resistor is not needed. While this device is designed for open drain
applications, the device can also translate push-pull CMOS logic outputs.
