The EL0631(TA) is a surface mounted Optocouplers manufactured by Everlight that is RoHS (Restriction of Hazardous Substances) compliant. This Optocouplers is a component used to transmit electrical signals between two isolated circuits, allowing for safety, general galvanic isolation, and noise protection. The EL0631(TA) features an 8-pin SMD type package that features two LEDs on one side that are optically coupled to a photosensitive transistor on the other side. It is typically used in low speed circuits that require isolation when connecting two different circuits.
