DESCRIPTION
The IL74 is an optically coupled pair with a Gal-
lium 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 gound
loop and noise problems. Also it can be used to
replace relays and transformers in many digital
interface applications, as well as analog applica-
tions such as CRT modulation.
The ILD74 has two isolated channels in a single
DIP package; the ILQ74 has four isolated chan-
nels per package.
