DESCRIPTION
The ILD/Q3 are optically coupled isolated pairs employing GaAs
infrared LEDs and silicon NPN phototransistor. Signal information,
including a DC level, can be transmitted by the drive while maintain-
ing a high degree of electrical isolation between input and output.
The ILD/Q3 are especially designed for driving medium-speed logic
and can be used to eliminate troublesome ground loop and noise
problems. Also these couplers can be used to replace relays and
transformers in many digital interface applications such as CRT
modulation. The ILD3 has two isolated channels in a single DIP
package and the ILQ3 has four isolated channels per package.
