Overview
The TXS0108EPWR is an 8-bit non-inverting bidirectional voltage-level translator produced by Texas Instruments. This device is designed to facilitate low-voltage translation between different voltage nodes, making it highly versatile for various electronic systems. It uses two separate configurable power-supply rails, allowing for voltage translation between 1.4V to 3.6V on the A port and 1.65V to 5.5V on the B port. This capability enables the device to support a wide range of digital systems and devices, including handsets, cell phones, iPads, and desktop computers.
