PCA9517DGKR

/ORDERING INFORMATION 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 (up-translation/down-translation) between low voltages (down to 0.9 V) and higher voltages (2.7 V to 5.5 V) in mixed-mode applications. This device enables I2C and similar bus systems to be extended, without degradation of performance even during level shifting.
