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 3750Vrms.
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.

1.6 General Conditions
Unless otherwise specified, minimum and maximum values are guaranteed by production testing requirements.
Typical values are characteristic of the device at 25°C, and are the result of engineering evaluations. They are
provided for information purposes only, and are not part of the manufacturing testing requirements. Specifications
cover the operating temperature range TA = -40°C to +85°C, unless otherwise specified.
Side A is the same as Side B, and Channel 1 is the same as Channel 2; therefore, the electrical and timing
specifications apply to both Sides/Channels.

4 Functional Description
4.1 Introduction
The CPC5001 combines the functions of two input
buffer/LED driver gates and two unidirectional logic
optoisolators in a single 8-pin package. The isolators
are arranged for one input and one output at each side
of the isolation barrier, which enables Channel 1 to
send signals from side A to Side B, and Channel 2 to
send signals from the Side B to the Side A. If different
supply voltage levels are used at each side, then the
part, in conjunction with its external pullup resistors,
will perform logic level translation for VDD between
2.7V and 5.5V at either side.
The part provides galvanic isolation for voltages up to
3750Vrms. Its CMOS circuitry includes a bandgap
reference to ensure that the LEDs receive consistent
6
drive current levels over the allowed range of VDD
voltages. The supply currents at IDDA and IDDB are
much smaller than those required by bipolar solutions,
and are stable over temperature. The circuits also
ensure that the IDD current into each VDD package pin
remains constant for both high and low input signals.
This can greatly reduce the size of external decoupling
capacitors when compared with optoisolators
fabricated in a bipolar process wherein the supply
current can double when the LED is on.
The rotationally symmetric pinout ensures that the
part operates normally even if installed with 180°
rotation.

5 Manufacturing Information
5.1 Moisture Sensitivity
All plastic encapsulated semiconductor packages are susceptible to moisture ingression. IXYS Integrated
Circuits Division classified all of its plastic encapsulated devices for moisture sensitivity according to the
latest version of the joint industry standard, IPC/JEDEC J-STD-020, in force at the time of product
evaluation. We test all of our products to the maximum conditions set forth in the standard, and guarantee
proper operation of our devices when handled according to the limitations and information in that standard as well as
to any limitations set forth in the information or standards referenced below.
Failure to adhere to the warnings or limitations as established by the listed specifications could result in reduced
product performance, reduction of operable life, and/or reduction of overall reliability.
This product carries a Moisture Sensitivity Level (MSL) rating as shown below, and should be handled according to
the requirements of the latest version of the joint industry standard IPC/JEDEC J-STD-033.

5.2 ESD Sensitivity
This product is ESD Sensitive, and should be handled according to the industry standard
JESD-625.
5.3 Reflow Profile
This product has a maximum body temperature and time rating as shown below. All other guidelines of
J-STD-020 must be observed.

5.4 Board Wash
IXYS Integrated Circuits Division recommends the use of no-clean flux formulations. However, board washing to
remove flux residue is acceptable. Since IXYS Integrated Circuits Division employs the use of silicone coating as an
optical waveguide in many of its optically isolated products, the use of a short drying bake may be necessary if a wash
is used after solder reflow processes. Chlorine-based or Fluorine-based solvents or fluxes should not be used.
Cleaning methods that employ ultrasonic energy should not be used.
