Level shifter circuits are the bridges that connect low core voltage components to high I/O interface voltage circuits. The UM320X and UM330X series level translator are designed to cost effectively address these voltage translation needs with high integration components. UM330X series are buffered type auto direction sensing voltage translator architectures, while UM320X series are switch type auto direction sensing voltage translator architectures. Neither type of architecture requires a DIR control signal to establish the direction of data flow. Read this paper to learn more.
