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
Side A. It provides galvanic isolation up to 3750V
rms
.
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.
