TXS0108E 8-Channel Bidirectional Logic Level Converter Nylon LED flashes digitalWrite(LedProvide 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
