Optocoupler, Phototransistor Output

(Single, Dual, Quad Channel)

IL74/ILD74/ILQ74

Vishay Semiconductors

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.
