CPC5903 - Optically Isolated I2C Bus Repeater

Description

The CPC5903 is a dual, optically isolated, logic-bus repeater.

It isolates two open-drain logic signals while providing 3750Vrms of galvanic isolation.

Features

  • Bidirectionally Buffers I2C SDA Signal.
  • Extends and Isolates I2C Interfaces.
  • Standard-mode and Fast-mode I2C Side B Fast-mode Compatible VDDB > 4.5V.
  • Operates on 2.7V to 5.5V.
  • Voltage Level Translation.
  • Slew-Limited Drivers Reduce EMI.
  • Powerdown to Hi-Z Does Not Load I2C.
  • 3750Vrms Galvanic Isolation.
  • Single 8-pin Surface-Mount Package.
  • Flammability Rating UL 95 V-0.
