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.
