Description
The IL250/ 251/ 252/ ILD250/ 251/ 252 are bidirec-
tional input optically coupled isolators consisting of
two Gallium Arsenide infrared LEDs coupled to a sili-
con NPN phototransistor per channel.
The IL250/ ILD/250 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 optocou-
plers. The ILD250/ ILD251/ ILD252 has two isolated
channels in a single DIP package.
