PCA9517A
Level-Translating I²C-Bus
Repeater
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
• Open−Drain Inputs/Outputs
• Lock−up 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 High−Impedance I²C−bus Pins
• A Side Operating Supply Voltage Range of 0.9 V to 5.5 V
• B side Operating Supply Voltage Range of 2.7 V to 5.5 V
• 5 V Tolerant I²C−bus and Enable Pins
• Available in: Micro−8, SOIC8
• ESD Performance: 8 kV HBM, 700 V MM, 2000 V CDM
• These are Pb−Free Devices
