CPC5902 2 Optically Isolated I C Bus Repeater INTEGRATED CIRCUITS DIVISION Features Description 2 Bidirectionally Buffers Both I C Signals IXYS Integrated Circuits CPC5902 is a dual, optically isolated, bidirectional logic-bus repeater. It galvanically Glitch-Free Operation 2 isolates two open-drain logic signals, and provides a Extends and Isolates I C Interfaces 2 galvanic isolation of 3750V . When the two sides Standard- and Fast-mode I C rms 2 supply voltages are configured with different voltages, Side B Fast-mode I C Compliant V > 4.5V DDB the CPC5902 also functions as a logic level translator Very Low EM and RF Generation - No Internal Clock for levels as low as 2.7V or as high as 5.5V. SMBus Compatible V = 3.3V DDB Operates on 2.7V to 5.5V, Enabling Level Translation Unlike transformer or capacitive isolators, the optically Slew-Limited Drivers Reduce EMI isolated repeaters pass DC signals, and do not need 2 Powerdown to Hi-Z Doesn t Load I C to be clocked periodically to sustain the logic states. 3750V Galvanic Isolation rms Buffered signals will always return to their proper value Flammability Rating UL 94 V-0 after a transient interruption on either side.
