DESCRIPTION
The IL250, IL251, IL252, ILD250, ILD251, ILD252 are bidirectional input optically coupled isolators consisting of two gallium arsenide infrared LEDs coupled to a silicon NPN phototransistor per channel.
The IL250, ILD250 has a minimum CTR of 50 %, the IL251, ILD251 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 ILD250, ILD251, ILD252 has two isolated channels in a single DIP package.
