Logic Level 8-Channel Bi-directional Converter TXB0108 wearable led and signal lightsBecause 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. Although one can use resistors to make a divider, for high speed transfers, the resistors can add a lot of slew and cause havoc that is tough to debug. For that reason, we like using 4050 74LVX245 series and similar logic
