Description

The CPC5001 is a dual, non-inverting digital optical

isolator with buffered-logic inputs and open-drain

outputs. Channel 1 propagates a signal from Side A to

Side B, while Channel 2 sends a signal from Side B to

When the two sides are powered by supplies with

different voltages, it also functions as a logic level

translator for supply voltages as low as 2.7V or as high

as 5.5V. Available in 8-pin DIP and surface mount

packages, it functionally replaces two logic buffers and

two single-channel optoisolators. Internal bandgap

references regulate the LED drive currents to 3mA to

reduce peak power requirements.

Unlike transformer or capacitive isolators, optical

isolation passes DC signals, and does not need to be

clocked periodically to refresh state. Buffered signals

will always return to their proper value after a transient

interruption at either side.
