This logic level breakout safely translates digital signals between 1.8V, 3.3V, and 5V device and can be used in a breadboard once soldered.

The Logic Level Converter TXB0104 Breakout safely interfaces components operating at different voltages. The TI TXB0104 IC provides four bidirectional channels, bridging low-voltage microcontrollers (1.8V – 3.3V) with higher-voltage peripherals up to 5V. Its auto-direction sensing simplifies data transfer without extra direction pins, ensuring reliable communication across mixed-voltage systems.

The TXB0104 handles push-pull and open-drain signals, supporting SPI, I2C, UART, and other digital interfaces. All channels are fully bidirectional, allowing simultaneous two-way communication. The compact breakout format makes it easy to integrate into breadboards or custom PCBs.

Ideal for connecting sensors or modules of varying voltages, this breakout ensures safe, stable, and flexible logic-level translation for any project.
