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
provides a galvanic isolation of 3750V
rms
. 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, 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.
