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.
