Overview
The TXS0104EPWR is a 4-bit bidirectional voltage translator produced by Texas Instruments. This component is designed to facilitate data transfer between different voltage levels, making it highly versatile in various electronic applications. It features two independent power supply lines, allowing it to operate with voltages ranging from 1.65 V to 3.6 V on the A port and from 2.3 V to 5.5 V on the B port. This flexibility enables smooth data translation between different voltage nodes such as 1.8 V, 2.5 V, 3.3 V, and 5 V.
