Description

Optocoupler, Phototransistor Output, AC Input, with Base Connection

The IL251 are bidirectional input optically coupled isolators consisting of two Gallium Arsenide infrared LEDs coupled to a silicon NPN phototransistor per channel.

The IL251 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 IL251 are single channel optocouplers. The IL251 has two isolated channels in a single DIP package.
