TR115
Telecommunications Switch
Optocoupler/1 Form A Relay
The TR115 is a dual function circuit designed specifically as a telecommunications switch. It consists an optically isolated solid state relay
separated from an optocoupler. 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.
