DESCRIPTION
The ILD/Q1/2/5 are optically coupled isolated pairs employing GaAs infra-
red LEDs and silicon NPN phototransistor. Signal information, including a
DC level, can be transmitted by the drive while maintaining a high degree
of electrical isolation between input and output. The ILD/Q1/2/5 are espe-
cially designed for driving medium-speed logic and can be used to elimi-
nate troublesome ground loop and noise problems. Also these couplers
can be used to replace relays and transformers in many digital interface
applications such as CRT modulation. The ILD1/2/5 has two isolated chan-
nels in a single DIP package and the ILQ1/2/5 has four isolated channels
per package.

“How to Use Optocoupler Normalized Curves”.
