CPC5903GSTR - Optically Isolated I2C Bus Repeater

Download the CPC5903GSTR datasheet PDF. This datasheet also covers the CPC5903 variant, as both devices belong to the same optically isolated i2c bus repeater family and are provided as variant models within a single manufacturer datasheet.

General Description

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

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

Key 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.
