The SparkFun 8 Channel Level Shifter Breakout features the TXS01018E™ 8-bit, bi-directional logic level translator from Texas Instruments. This board allows you to easily shift logic between devices running at different common microcontroller voltages such as 1.8V, 3.3V and 5V. The TXS0108E can transmit data between ports at max speeds of 110Mbps (push/pull) or 1.2Mbps (open drain) so you can use a 3.3V SPI device with a 5V microcontroller like the SparkFun RedBoard Plus without sacrificing data transmission speeds.
The TXS0108E accepts a supply voltage range between 1.4V to 3.6V on Port A and 1.65V to 5.5V on Port B. This breakout routes all of the TXS01018E's pins to a pair of 0.1"-spaced plated through-hole headers for easy access with some basic soldering.
Features:
- Bi-Directional Level-Shifting
- Open-Drain and Push-Pull Applications
- Max Data Rates:
- 110 Mbps (push-pull)
- 1.2 Mbps (open-drain)
- Supply Voltage Range:
- Port A: 1.4V to 3.6V
- Port B: 1.65V to 5.5V

Jargon buster
Plain-language definitions for the technical terms used above.
- breakout
- A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
