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.
FEATURES
• ^{Function integration (SSR + Optocoupler) in compact package}
• ^{20 ohms max on-resistance (Relay Portion)}
• ^{120mA max continuous load current (Relay Portion)}
• ^{Low input control current (2.5mA TYP, Relay Portion)}
• ^{High Input-Output Isolation}
• ^{Solid State Reliability}
