Optocoupler, Phototransistor Output, AC Input,

with Base Connection

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.

FEATURES

• AC or polarity insensitive inputs
