 Next pic shows an example of using an I2C voltage level translator to bridge the communication between two different supply voltages. There are two sets of pullups, one for each voltage level. As a common voltage translator, the PCA9306 allows for communication between different supply levels: Next pic shows an example of using an I2C voltage level translator to bridge the communication between two different supply voltages.
