SparkFun Level Shifter - 8 Channel (TXS0108E)

The SparkFun 8 Channel Level Shifter Breakout features the TXS0108E 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 TXS0108E's pins to a pair of 0.1"-spaced plated through-hole headers for easy access with some basic soldering.

  • 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

Core Skill: Soldering

This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.

1 Soldering

Skill Level: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

Core Skill: Programming

If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.

2 Programming

Skill Level: Rookie - You will need a better fundamental understand of what code is, and how it works. You will be using beginner-level software and development tools like Arduino. You will be dealing directly with code, but numerous examples and libraries are available. Sensors or shields will communicate with serial or TTL.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

2 Electrical Prototyping

Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.
