1 STS71 DESCRIPTION The STS71 is a multi-function telecommunications switch. It combines a 1 Form 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 rray 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 STS71 an ideal choice in telecom circuits where function integration and reduction of board space are essential. FETURES Miniature 16pin SOIC package Function integration, including Zener Diode protection High Blocking Voltage (4V, relay portion) Low input control current (2.5m TYP, relay portion) Low On-Resistance (3 ohms MX, relay portion) High Load Current (12m MX, relay portion) High Input - Ouptut Isolation (1.5kV MIN, relay portion) Long life / high reliability OPTIONS/SUFFIXES* PPLICTIONS Telecom switching PCMCI cards Fax/modem modules Set-top boxes D arrangements Hookswitch Loop current detect Pulse dialing BSOLUTE MXIMUM RTINGS* -TR Tape & Reel Packaging PRMETER UNIT MIN TYP MX NOTE: Suffixes listed above are not included in marking on device for part number identification.
