Description
The IL74/ ILD74/ ILQ74 is an optically coupled pair
with a GaAIAs 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/ ILD74/ ILQ74 is especially 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 CTR modulation.
The ILD74 has two isolated channels in a single DIP
package; the ILQ74 has four isolated channels per
package.

Absolute Maximum Ratings
T
= 25 °C, unless otherwise specified
amb
Stresses in excess of the absolute Maximum Ratings can cause permanent damage to the device. Functional operation of the device is
not implied at these or any other conditions in excess of those given in the operational sections of this document. Exposure to absolute
Maximum Rating for extended periods of the time can adversely affect reliability.
