Abstract

The TXB010x and the TXB030x are categorized under the TXB-Type translators supporting level shifting of auto-bidirectional signals. While both devices share similar architecture, the differences in one-shot architecture and buffering circuitry enable them to support different use cases. To achieve optimized signal integrity, system designers need to be mindful of the output loading considerations, as well as other guidelines documented in this application note.
