Optocoupler, Photodarlington Output

(Single, Dual, Quad Channel)

IL30/IL31/IL55/ILD30/ILD31/ILD55/ILQ30/ILQ31/ILQ55

Vishay Semiconductors

DESCRIPTION

The IL30/IL31/IL55 single, ILD30/ILD31/ILD55 dual, and

ILQ30/ILQ31/ILQ55 quad are optically coupled isolators with

gallium

arsenide

infrared

emitters

and

silicon

photodarlington sensors. Switching can be achieved while

maintaining a high degree of isolation between driving and

load circuits, with no crosstalk between channels. These

optocouplers can be used to replace reed and mercury

relays with advantages of long life, high speed switching and

elimination of magnetic fields.

The IL30/IL31/IL55 are equivalent to MCA230/MCA231/

MCA255. The ILD30/ILD31/ILD55 are designed to reduce

board space requirements in high density applications.
