Littelfuse, Inc. Power Semiconductors & Control ICs - Integrated Circuits - Digital Bus Driver ICs - Series: I2C-Bus Repeaters - CPC5903 CPC5903

Our Optically Isolated I2C Bus Repeater is the industry's first integrated optical solution for I2C bus design that: Minimizes PC board space usage Reduces parts count for this function Unlike magnetically isolated digital isolator ICs, this optical solution: Needs no internal clocking, which is a primary source of EMI/RFI interference Supports direct static-state buffering without refresh clocks The CPC5904 features excellent reliability and very long operational life. Contact the factory for long-term reliability information. Bidirectionally Buffers Both I2C Signals Glitch-Free Operation Extends and Isolates I2C Interfaces Standard-mode, Fast-mode and Fast-mode Plus I2C Side B Fast-mode I2C Compliant (Vddb of 4.5 V to 5.5 V) No Internal Clock Ensures Very Low EM and RF Generation SMBus Compatible (Vddb of 3.3V) Operates on 2.7 V to 5.5 V, Enabling Level Translation Slew-Limited Drivers Reduce EMI Powerdown to Hi-Z Doesn't Load I2C
