Description

These high gain series couplers

use a Light Emitting Diode and an

integrated high gain photodetec-

tor to provide extremely high

current transfer ratio between

input and output. Separate pins

for the photodiode and output

stage result in TTL compatible

saturation voltages and high

speed operation. Where desired

tied together to achieve conven-

tional photodarlington operation.

A base access terminal allows a

gain bandwidth adjustment to be

made.

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 rating is for HCNW139/138 and Option 020 (6N139/138) products only.

A 0.1

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