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.
