PCA9517 Level-Translating I2C Bus Repeater

This dual bidirectional I2C buffer is operational at 2.7 V to 5.5 V. The PCA9517 is a BiCMOS integrated circuit intended for I2C bus and SMBus systems. It can also provide bidirectional voltage-level translation (uptranslation/down-translation) between low voltages (down to 0.9 V) and higher voltage.
