PCA9617A Datasheet, PDF (1/15 Pages) NXP Semiconductors – Level translating Fm+ I2C-bus repeater

PCA9617A
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 V_CC(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
• Powered−off High−impedance I²C−bus Pins
• Available in: Micro−8,
• ESD Performance: 8 kV HBM, 800 V MM
2000 V CDM
• These Devices are Pb−Free, Halogen Free/BFR Free and are RoHS
Compliant
