Description

IXYS Integrated Circuits’ 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 . When the two sides’

rms

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.

> 4.5V

DDB

• Operates on 2.7V to 5.5V, Enabling Level Translation

• Slew-Limited Drivers Reduce EMI

• Powerdown to Hi-Z Doesn't Load I C

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.
