Optocoupler, Phototransistor Output, AC Input,
with Base Connection
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.
