Selecting the right autobidirectional voltage translator for your design

This short video provides an overview of our three autobidirectional families (TXB, TXS and LSF) and when to use them. 

  • TXB is designed to preserve signal integrity in push-pull interfaces.
  • TXS works with both push-pull and open-drain interfaces and includes integrated pull-up resistors.
  • LSF is the most flexible for discrete designs.


For systems requiring higher drive strength or higher data rates, we recommend using direction controlled or unidirectional voltage level translators.

Featured evaluation modules 

AXC-SMALLPKG1EVM

Evaluation module for small package direction-controlled translation devices.

Supports SN74AXC8T245 in the RJW package and SN74AXC1T45 in DEA & DTQ packages; populates the SN74AVC4T245 in the RSV package. 

LSF-EVM

1-to 8-bit LSF translator family evaluation module.

The LSF family of devices are level translators that support a voltage range of 0.95-V and 5-V and provide multi-voltage bidirectional translation without a direction pin.

TXS-EVM

1-to 8-bit TXS translator family evaluation module.

TXS-EVM supports single, dual, quad and octal channel TXS devices. TXS devices belong to the auto bidirectional voltage level translation family with an operating voltage between 1.2-V and 5.5-V.
