DESCRIPTION

The ILD1, ILD2, ILD5, ILQ1, ILQ2 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 maintaining a

high degree of electrical isolation between input and output.

The ILD1, ILD2, ILD5, ILQ1, ILQ2 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 CTR modulation.

The ILD1, ILD2, ILD5 have two isolated channels in a single

DIP package and the ILQ1, ILQ2 have four isolated channels

per package.
