DESCRIPTION
The 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 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.
FEATURES
• ILD74, ILQ74 TTL compatible
• Transfer ratio, 35 % typical

Note
• 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 ratings for extended periods of the time can adversely affect reliability.
