00 — Overview

What the TXS0108E family does

The TXS0108E is an 8-bit bi-directional, level-shifting voltage translator designed for open-drain and push-pull applications. It operates with independent power supplies ranging from 1.4V to 5.5V across its A and B ports, supporting data rates up to 110Mbps for push-pull and 1.2Mbps for open-drain configurations. This device requires no direction-control signal or power-supply sequencing, making it ideal for connecting handsets, smartphones, tablets, and desktop PCs to different voltage domains. It features robust ESD protection exceeding 2000V for the human body model and includes multiple package options to suit various board space constraints.
