Selecting the right autobidirectional voltage translator for your design

Learn how to overcome common challenges by utilizing logic devices to aid in optimizing system design.

This short Logic Minute training video provides an overview of our three autobidirectional families (TXB, TXS and LSF) and when to use them. We also offer eight videos on the LSF family and two on the basics of logic on translation in the training series.
