DESCRIPTION

The IL250, IL251, IL252, ILD252 are bidirectional input

optically coupled isolators consisting of two gallium

arsenide infrared LEDs coupled to a silicon NPN

phototransistor per channel.

The IL250 has a minimum CTR of 50 , the IL251 has a

minimum CTR of 20 , and the IL252, ILD252 has a

minimum CTR of 100 .

The IL250, IL251, IL252 are single channel optocouplers.

The ILD252 has two isolated channels in a single DIP

package.
