HCPL-070A-000E

Very Low Power Consumption High Gain Optocouplers

Avago Technologies 

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

configuration 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, the

VCC and VO terminals may be tied together to achieve

conventional 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 VCC ≥ 3 V.

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.
