Voltage level translators
Resolve input/output voltage difference with level shifter ICs
Our industry-leading portfolio of voltage level translators, or logic level shifters, solves incompatibility differences between different power domains. Browse our wide range of direction-controlled voltage translators, auto bidirectional voltage translators and unidirectional voltage translators.
Voltage translation for standard bus and backplane applications.
Voltage Translation Buying Guide
Unsure of which voltage translator class to use for your design? Our buying guide will help you find the logic level shifter for your system design requirements.
- Direction-controlled translators are the most flexible, easy to-use, and offer the best signal integrity. Best for one-to-one communication between devices such as RGMII, and with protocols featuring one master.
- Auto bidirectional translators are for interfaces that require that the I/O pins of each device be open-drain or open-collector so that any device can start to transmit on the bus.
- Unidirectional translators are best when transmitted signals only need to go one direction. Typical examples are reset signals and clock synchronization signals.
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.
Featured logic shifters
Featured evaluation modules
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.
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.
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.
