Description

These high gain series couplers use

a Light Emitting Diode and an

integrated high gain photodetector

to provide extremely high current

transfer ratio between input and

output. Separate pins for the

photodiode and output stage result

in LVTTL compatible saturation

voltages and high speed operation.

Where desired, the V

terminals may be tied together to

achieve conventional photo-

Functional Diagram

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

darlington operation. A base

access terminal allows a gain

bandwidth adjustment to be

made.

These optocouplers are for use in

LVTTL/LVCMOS or other low

power applications. A 400%

minimum current transfer ratio is

guaranteed over 0 to +70˚C

operating range for only 0.5 mA

of LED current.
