Agilent HCPL-7723 & HCPL-0723

50 MBd 2 ns PWD

High Speed CMOS Optocoupler

Data Sheet

Description

Available in either 8-pin DIP or

SO-8 package style respectively, the

HCPL-7723 or HCPL-0723

optocoupler utilize the latest CMOS

IC technology to achieve out-

standing speed performance of

minimum 50 MBd data rate and

2 ns maximum pulse width

distortion.

Basic building blocks of HCPL-

7723/0723 are a CMOS LED

driver IC, a high speed LED and a

CMOS detector IC. A CMOS logic

input signal controls the LED

driver IC, which supplies current

to the LED. The detector IC

incorporates an integrated

photodiode, a high speed

transimpedance amplifier, and a

voltage comparator with an

output driver.

* PIN 3 IS THE ANODE OF THE INTERNAL LED AND MUST BE LEFT

UNCONNECTED FOR GUARANTEED DATASHEET PERFORMANCE.

PIN 7 IS NOT CONNECTED INTERNALLY.

** A 0.1 µF BYPASS CAPACITOR MUST BE CONNECTED BETWEEN

PINS 1 AND 4, AND 5 AND 8.

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.
