4-channel I2C-safe Bi-directional Logic Level Converter

4-channel I2C-safe Bi-directional Logic Level ConverterBecause 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. We do have some other handy level shifters in the shop, from the DIP 74LVC245 to the fancy bi directional TXB0108. However, neither of these are happy to work with I2C, which uses a funky pull up system to transfer data
