ht12A-E series chips for infrared control undefined at proteus!

[frukoglan]

Hi everyone! I need some help about ht12A-E series chips for my project. I can't find these chips at proteus. Because of that ı can't simulate my project's circuit at proteus. Can anybody know how ı can use ht12a chips at proteus? OR Is there any alternative of ht12A chips for same mission?

By the way my project was 4-channel infrared relay control.
