TCA9517DGKR
Texas Instruments
The Texas Instruments TCA9517DGKR is a bidirectional I2C bus buffer and level shifter translating between two voltage domains from 0.9 V to 5.5 V. It provides two channels with hot-swap and stuck-bus recovery in an 8-pin VSSOP, for multi-voltage I2C systems and hot-swap backplanes.
