8 Channel logic level converter TXB0108
Because the Arduino (and Basic Stamp) are 5V devices, and most modern sensors, displays, flash cards and modes are 3.3V-only, many makers find that they need to perform level shifting/conversion to protect the 3.3V device from 5V.
That’s where this lovely chip, the TXB0108 bi-directional level converter comes in! 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).
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!
