Description

These dual channel optocouplers

contain a separated pair of GaAsP

light emitting diodes optically

coupled to a pair of integrated

high gain photo detectors. They

provide extremely high current

transfer ratio and excellent input-

output common mode transient

immunity. A separate pin for the

photodiodes and first gain stages

(VCC) permits lower output satura-

tion voltage and higher speed

operation than possible with

conventional photodarlington

type optocouplers. In addition,

VCC may be as low as 1.6 V

Functional Diagram

CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to

prevent damage and/or degradation which may be induced by ESD.

*5000 V rms/1 minute withstand voltage rating is for Option 020 (HCPL-2730, HCLP-2731) products only.

A 0.1 µF bypass capacitor connected between pins 5 and 8 is recommended.

These dual channel optocouplers

are available in an 8-Pin DIP and

in an industry standard SO-8

package. The following is a cross

reference table listing the 8-Pin

DIP part number and the

electrically equivalent SOIC-8 part

number.

8-Pin DIP SO-8

HCPL-2730 HCPL-0730

HCPL-2731 HCPL-0731

The SO-8 does not require

“through holes” in a PCB. This

package occupies approximately

one-third the footprint area of the

standard dual-in-line package.

The lead profile is designed to be

compatible with standard surface

mount processes.

Guaranteed operation at low input

currents and the high current

transfer ratio (CTR) reduce the

magnitude and effects of CTR

degradation.

The outstanding high temperature

performance of this split

Darlington type output amplifier

results from the inclusion of an

integrated emitter-base bypass

resistor which shunts photodiode

and first stage leakage currents to

ground.

The HCPL-2731/0731 have a

400% minimum CTR at an input

current of only 0.5 mA making it

ideal for use in low input current

applications such as MOS, CMOS,

and low power logic interfacing or

RS232C data transmission

systems. In addition, the high

CTR and high output current

capability make this device

extremely useful in applications

where a high fanout is required.

Compatibility with high voltage

CMOS logic systems is guaranteed

by the 18 V VCC and VO specifica-

tions and by testing output high

leakage (IOH) at 18 V.

The HCPL-2730/0730 are speci-

fied at an input current of 1.6 mA

and have a 7 V VCC and VO rating.

The 300% minimum CTR allows

TTL to TTL interfacing at this

input current.

Important specifications such as

CTR, leakage current, and output

saturation voltage are guaranteed

over the 0°C to 70°C temperature

range to allow trouble-free system

operation. Selection for lower

input currents down to 250 µA is

available upon request.

Notes:

1. Pin 5 should be the most negative

voltage at the detector side.

2. Each channel.

3. DC CURRENT TRANSFER RATIO

(CTR) is defined as the ratio of output

collector current, IO, to the forward

LED input current, IF, times 100%.

4. Device considered a two-terminal

device: pins 1, 2, 3, and 4 shorted

together, and pins 5, 6, 7, and 8

shorted together.

5. Measured between pins 1 and 2

shorted together, and pins 3 and 4

shorted together.

6. Common mode transient immunity in a

Logic High level is the maximum

tolerable (positive) dV

CM/dt of the

A = 25°C

common mode pulse, VCM, to assure

that the output will remain in a Logic

High state (i.e., VO > 2.0 V). Common

mode transient immunity in a Logic

Low level is the maximum tolerable

(negative) dVCM/dt of the common

mode pulse, VCM, to assure that the

output will remain in a Logic Low state

(i.e., VO < 0.8 V).

7. In applications where dV/dt may

exceed 50,000 V/µs (such as static

discharge) a series resistor, RCC,

should be included to protect the

detector IC from destructively high

surge currents. The recommended

value is RCC = 110 Ω.

8. Use of a 0.1 µF bypass capacitor

connected between pins 5 and 8

adjacent to the device is

recommended.

9. In accordance with UL 1577, each

optocoupler is proof tested by

applying an insulation test voltage

> 4500 V rms for 1 second (leakage

detection current limit, II-O < 5 µA).

10. In accordance with UL 1577, each

optocoupler is proof tested by

applying an insulation test voltage

> 6000 V rms for 1 second (leakage

detection current limit, II-O < 5 µA).

11. Measured between the LED anode and

cathode shorted together and pins 5

through 8 shorted together.

12. Derate linearly above 65°C free-air

temperature at a rate of 2.3 mW/°C for

the SO-8 package.
