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 detec-
tion and monitoring.
