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