Level-Translating Fm+ I2C-Bus Repeater

The PCA9617A is an I2C−bus repeater that provides level shifting between low voltage (0.8 V to 5.5 V) and higher voltage (2.2 V to 5.5 V) for Fast−Mode Plus (Fm+) I2C−bus or SMBus applications.

FEATUREs
• Two Channel, Bidirectional Buffer Isolates Capacitance and Allows
   540 pF on Either Side of the Device at 1 MHz and up to 4000 pF at
   Lower Speeds
• Voltage Level Translation from 0.8 V to 5.5 V and from 2.2 V to
   5.5 V
• Footprint and Functional replacement for PCA9517A at Fast−mode
   speeds
• Port A Operating Supply Voltage Range of 0.8 V to 5.5 V with
   Normal Levels
• Port B Operating Supply Voltage Range of 2.2 V to 5.5 V with Static
   Offset Level
• 5 V Tolerant I2C−bus and Enable Pins
• 0 Hz to 1000 kHz Clock Frequency (the Maximum System Operating
   Frequency May be Less than 1000 kHz Because of the Delays Added
   by the Repeater)
• Active HIGH Repeater Enable Input Feferenced to VCC(B)
• Open−Drain Input/Outputs
• Latching Free Operation
• Supports Arbitration and Clock Stretching Across the Repeater
• Accommodates Standard−mode, Fast−mode and Fast−mode Plus
   I2C−bus Devices, SMBus (Standard and High Power Mode), PMBus
   and Multiple Masters
