CPC5902 Series

Optically Isolated I²C Bus Repeater

IXYS Integrated Circuits Division

CPC5902 is a dual, optically isolated, bidirectional logic-bus repeater.

Product Description

CPC5902 is a dual, optically isolated, bidirectional logic-bus repeater. It galvanically isolates two open-drain logic signals, and provides a galvanic isolation of 3750Vrms. When the two sides’ supply voltages are configured with different voltages, the CPC5902 also functions as a logic level translator for levels as low as 2.7V or as high as 5.5V.

Unlike transformer or capacitive isolators, Clare’s optically isolated repeaters pass DC signals, and do not need to be clocked periodically to sustain the logic states. Buffered signals will always return to their proper value after a transient interruption on either side.

Features
  • Bidirectional Buffers Both I²C Signals
  • Glitch-Free Operation
