TCA9517 Level-Shifting I2C Bus Repeater

Texas Instruments TCA9517 Level-Shifting I²C Bus Repeater is a bi-directional buffer with level-shifting capabilities for I²C and SMBus systems. This repeater provides bi-directional voltage-level translation (up-translation/down-translation) between low voltages (down to 0.9V) and higher voltages (2.7V to 5.5V) in mixed-mode applications. The TCA9517 enables I²C and SMBus systems to be extended without performance degradation, even during level shifting.
