DESCRIPTION

The IL/ILD250/251/252 are bidirectional input optically coupled isolators

consisting of two Gallium Arsenide infrared LEDs coupled to a silicon NPN

phototransistor per channel.

The IL/ILD250 has a minimum CTR of 50%, the IL/ILD251 has a minimum

CTR of 20%, and the IL/ILD252 has a minimum CTR

of 100%.

The IL/IL250/1/2 are single channel optocouplers. The

ILD250/1/2 has two isolated channels in a single DIP package.

These optocouplers are ideal for applications requiring AC signal detection

and monitoring.
