Ask AI about this product
This level shifter board combines the ease-of-use of the bi-directional TXB0108 with an I2C-compatible FET design following NXP's app note.

This breakout has 4 BSS138 FETs with 10K pullups. It works down to 1.8V on the low side, and up to 10V on the high side. The 10K's do make the interface a little more sluggish than using a TXB0108 or 74LVC245 so we suggest checking those out if you need high-speed transfer.

While we designed it for use with I2C, this works as well forĀ  TTL Serial,Ā  slow <2MHz SPI, and any other digital interface both uni-directional and bidirectional. Comes with a fully assembled, and tested PCB with 4 full bidirectional converter lines as well as 2 pieces of 6-pin header you can solder on to plug into a breadboard or perfboard.
What is included with the product package?
The unit comes fully assembled and tested, with four bidirectional converter lines and two six pin headers that you can solder on to plug into a breadboard or perfboard.
What voltages are supported on the low and high sides?
The low side supports down to 1.8V and the high side supports up to 10V.
Is this suitable for I2C and can it be used for other interfaces?
Yes, it is designed for I2C with four BSS138 FETs and can also work for TTL Serial, slow less than 2 MHz SPI, and other digital interfaces both uni directional and bidirectional.
How does the 10K pullup affect performance and what are the alternatives for higher speed?
The 10K pullups can make the interface somewhat sluggish. For higher speed transfers consider faster options such as TXB0108 or 74LVC245.
Is the board assembled and tested before shipping?
Yes, the breakout is fully assembled and tested prior to shipment.
