Description

IXYS Integrated Circuits Division’s CPC5902 is a dual,

optically isolated, bidirectional logic-bus repeater. It

galvanically isolates two open-drain logic signals, and

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, the 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.
