DESCRIPTION
The IL74 is an optically coupled pair with a
Gallium Arsenide infrared LED and a silicon
NPN phototransistor. Signal information,
including a DC level, can be transmitted by the
device while maintaining a high degree of
electrical isolation between input and output.
The IL74 is especially designed for driving
medium-speed logic, where it may be used to
eliminate troublesome ground loop and noise
problems. Also it can be used to replace relays
and transformers in many digital interface
applications, as well as analog applications
such as CRT modulation.
The ILD74 has two isolated channels in a sin-
gle DIP package; the ILQ74 has four isolated
channels per package.
