CPC5903
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
Description
The CPC5903 is a dual, optically isolated, logic-bus repeater. It isolates two open-drain logic signals while providing 3750Vrms of galvanic isolation. When the two sides are powered by different supply voltages, it also functions as a logic level translator for levels as low as 2.7V or as high as 5.5V.
