ON Semiconductor 

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 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

• 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
