The SparkFun 8 Channel Level Shifter Breakout is an exceptional device that incorporates the TXS0108E™ 8-bit, bi-directional logic level translator from Texas Instruments. This innovative board facilitates the smooth shifting of logic between devices operating at varying microcontroller voltages such as 1.8V, 3.3V, and 5V. It can transmit data between ports at maximum speeds of 110Mbps (push/pull) or 1.2Mbps (open drain), making it ideal for integrating a 3.3V SPI device with a 5V microcontroller like the SparkFun RedBoard Plus, without compromising on data transmission speeds.
The TXS0108E is designed to accept a supply voltage range between 1.4V to 3.6V on Port A and 1.65V to 5.5V on Port B. The breakout on this board is designed to route all of the TXS0108E's pins to a pair of 2.54mm-spaced plated through-hole headers, which can be easily accessed with some basic soldering.
This SparkFun product offers bi-directional level-shifting, making it versatile for a range of applications. It is designed to work with both open-drain and push-pull applications. The maximum data rates it supports are 110 Mbps for push-pull applications and 1.2 Mbps for open-drain applications. The supply voltage range it can handle is 1.4V to 3.6V for Port A and 1.65V to 5.5V for Port B.
The SparkFun 8 Channel Level Shifter Breakout also comes with a range of helpful documents, including a schematic, eagle files, board dimensions, a hookup guide, a datasheet for the TXS0108E, and a GitHub Hardware Repository. These resources make it easier for users to understand and utilize the product to its full potential.
