Features

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

• Bidirectionally Buffers Both I C Signals

• Glitch-Free Operation

• Extends and Isolates I C Interfaces

provides a galvanic isolation of 3750V . When the

rms

• Standard- and Fast-mode I C

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.

Side B Fast-mode I C Compliant V

• Very Low EM and RF Generation - No Internal Clock

• SMBus Compatible V = 3.3V

> 4.5V

DDB

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.

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

• Slew-Limited Drivers Reduce EMI

• Powerdown to Hi-Z Doesn't Load I C

• 3750V
