FAQ: Logic and Voltage Translation > Voltage Translators >> Current FAQ
The LSF family of translators generates more questions than any other device in the translation portfolio. These devices are internally relatively simple, so we find it easier to explain how the whole part works rather than trying to answer every question that comes along. If your question doesn't get answered by the information provided in this page, please click the "Ask a related question" link at the top of the page and ask us directly.
This video series provides a quick look at how the LSF devices achieve auto-bidirectional translation. Each video is under 5 minutes.
