Description
The IL74/ ILD74/ ILQ74 is an optically coupled pair
with a GaAIAs infrared LED and a silicon NPN pho-
totransistor. 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/ ILD74/ ILQ74 is especially for driving
medium-speed logic, where it may be used to elimi-
nate troublesome ground loop and noise problems.
Also it can be used to replace relays and transformers
in many digital interface applications, as well as ana-
log applications such as CTR modulation.
The ILD74 has two isolated channels in a single DIP
package; the ILQ74 has four isolated channels per
package.
