9 Application and Implementation

NOTE

Information in the following applications sections is not part of the TI component

specification, and TI does not warrant its accuracy or completeness. TI’s customers are

responsible for determining suitability of components for their purposes. Customers should

validate and test their design implementation to confirm system functionality.

9.1 Application Information

The TXB0101 can be used in level-translation applications for interfacing devices or systems operating at

different interface voltages with one another. It can only translate push-pull CMOS logic outputs. If for open-drain

signal translation, please refer to TI TXS010X products. Any external pulldown or pullup resistors are

recommended larger than 50 k

Ω.
