Vishay Semiconductors
DESCRIPTION
The IL250/251/252/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 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.
