For complete documentation, see the data sheet
Product Description
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 Allows
400 pF on Either Side of the Device
• Voltage Level Translation from 0.9 V to 5.5 V and from 2.7 V to
5.5 V
• Footprint and Functional Replacement for PCA9515/15A
• I2C bus and SMBus Compatible
• Active HIGH Repeater Enable
• OpenDrain Inputs/Outputs
• Lockup Free Operation
• Supports Arbitration and Clock Stretching Across the Repeater, and
Multiple Masters
• I2C and SMBus SCL Clock Frequency up to 1 MHz (The maximum
system operating frequency may be less than 1 MHz because of the
delays added by the repeater.)
• Powered Off HighImpedance I2C bus Pins
