Features
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements
• Higher Reliability than Electromechanical Relays
• FCC Compatible
• VDE Compatible
• No EMI/RFI Generation
• Small 8-Pin Packages
• Flammability Rating UL 94 V-0
• Surface Mount and Tape & Reel Versions Available
The optically coupled outputs, that use patented
OptoMOS architecture, are controlled by a highly
efficient infrared LED.
This dual switch OptoMOS relay provides a more
compact design solution than discrete single-pole
relays in a variety of applications, and saves board
space by incorporating two switches in a single 8-pin
package.
