Description

These devices are very low power

consumption, high gain single

and dual channel optocouplers.

The HCPL-4701 represents the

single channel 8-Pin DIP configu-

ration and is pin compatible with

the industry standard 6N139. The

HCPL-4731 represents the dual

channel 8-Pin DIP configuration

and is pin compatible with the

popular standard HCPL-2731.

The HCPL-070A and HCPL-073A

are the equivalent single and dual

channel products in an SO-8

footprint. Each channel can be

driven with an input current as

low as 40

µA and has a typical

current transfer ratio of 3500%.

These high gain couplers use an

AlGaAs LED and an integrated

high gain photodetector to

provide an extremely high

current transfer ratio between

input and output. Separate pins

for the photodiode and output

stage results in TTL compatible

saturation voltages and high

speed operation. Where desired,

tied together to achieve conven-

tional Darlington operation

(single channel package only).

These devices are designed for

use in CMOS, LSTTL or other low

power applications. They are

especially well suited for ISDN

telephone interface and battery

operated applications due to the

low power consumption. A 700%

minimum current transfer ratio is

guaranteed from 0

°C to 70°C

operating temperature range at

40

µA of LED current and

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.
