Why Choose This Level Shifter?

Whether you’re building a sensor array, connecting a peripheral, or creating a multi‑device network, this TXS0108E shifter guarantees reliable communication across different voltage domains. Its bi‑directional nature eliminates the need for separate TX/RX level converters, saving space and simplifying your circuit design.

Easy Integration

1. Connect the 3.3 V side to your microcontroller’s I2C/SPI/UART pins.
2. Connect the 5 V side to the external device.
3. Power the module with a single 3.3 V or 5 V supply (VCC1 and VCC2 can be tied together).
4. The device automatically detects direction and adjusts the level conversion accordingly.

Ideal Applications

• Arduino projects requiring 5 V sensors or modules
• ESP32 or Raspberry Pi interfacing with 3.3 V I2C/SPI devices
• Robotics, IoT, and hobby electronics kits
• Professional prototyping and PCB design

Enhance your electronics workflow with the TXS0108E Bi‑Directional Logic Level Shifter – a compact, high‑performance solution for all your 3.3 V to 5 V communication needs.
