TXS0108E 8-Channel Bidirectional Logic Level ConverterSKU: ELC3026
Provide two-way communication capability at varied voltage levels to your electronics project with the TXS0108E. This chip perform bidirectional level shifting from pretty much any voltage to any voltage and will auto-detect the direction. Only thing that doesn't work well with this chip is i2c (because it uses strong pullups which confuse auto-direction sensor). If you need to use pullups, you can but they should be at least 50K ohm - the ones internal to AVRs/Arduino are about 100K ohm so those are OK! Its a little more luxurious than a 74LVC245 but if you just don't want to worry about directional pins this is a life saver!
Since this chip is a special bi-directional level shifter it does not have strong output pins that can drive LEDs or long cables, it's meant to sit on a breadboard between two logic chips!
This breakout saves you from having to solder the very fine pitch packages that this chip comes with. We also add 0.1uF caps onto both sides. You just need to make sure you enable the chip by pulling OE pin high.
