PCA9517A:  Level Translating I2C-BUS

The PCA9517A is an I2C bus repeater that provides level shifting between low voltage (down to 0.9 V) and higher voltage (2.7 V to 5.5 V) for I2C bus or SMBus applications.

Features
  • 2 Channel, Bidirectional Buffer Isolates Capacitance and Allows400 pF on Either Side of the Device
  • Voltage Level Translation from 0.9 V to 5.5 V and from 2.7 V to5.5 V
