Overview
The TXS0108EZXYR, produced by Texas Instruments, is an 8-bit bi-directional, level-shifting, voltage translator. This component is designed to facilitate communication between two different voltage domains without the need for a direction-control signal. It supports a wide range of supply voltages, making it versatile for various applications. The device can operate with supply voltages on the A port ranging from 1.4V to 3.6V and on the B port from 1.65V to 5.5V, enabling translation between different voltage nodes such as 1.5V, 1.8V, 2.5V, 3.3V, and 5V.
