| TR115 Telecommunications Switch Optocoupler/1 Form A Relay DESCRIPTION The TR115 is a dual function circuit designed specifically as a telecommunications switch. It consists an optically isolated solid state relay and an optically isolated optocoupler combined in a compact 8pin DIP package. The relay portion is composed of an LED on the input, optically coupled to a sensing circuit which drives two source-to-source DMOS transistors. The optocoupler portion of the package consists of two back-to-back LEDs that drive an output phototransistor.
