TXS0108E SCES642B – DECEMBER 2007 – REVISED SEPTEMBER 2008 ..................................................................................................................................... www.ti.com DESCRIPTION/ORDERING INFORMATION This 8-bit noninverting translator uses two separate configurable power-supply rails. The A port is designed to track VCCA. VCCA accepts any supply voltage from 1.2 V to 3.6 V. The B port is designed to track VCCB. VCCB accepts any supply voltage from 1.65 V to 5.5 V.

TXS0108E SCES642B – DECEMBER 2007 – REVISED SEPTEMBER 2008 ..................................................................................................................................... www.ti.com PRINCIPLES OF OPERATION Applications The TXS0108E can be used in level-translation applications for interfacing devices or systems operating at different interface voltages with one another. The TXS0108E is ideal for use in applications where an open-drain driver is connected to the data I/Os.

Similarly, during a falling edge, when transmitting data from B to A, the One-Shot (OS2) turns on NMOS transistor (N1) for a short-duration and this speeds up the high-to-low transition.
