STS710
Multifunction Telecommunications Switch
DESCRIPTION
The STS710 is a multi-function telecommunications switch. It combines a 1 Form A solid state relay, phototransistor, zener diode, darlington transistor and a bridge rectifier in a 16-pin SOIC package.The solid state relay is comprised of an infrared LED optically coupled to a Photo Diode Array that drives two back-to-back MOSFETs. The optocoupler consists of back-to-back infrared LEDs coupled to a Photo-Transistor. Its small outline and low height make the STS710 an ideal choice in telecom circuits where function integration and reduction of board space are essential.
