Features
• 3750Vrms Input/Output Isolation
• Low Drive Power Requirements
TTL/CMOS Compatible
Its optically coupled outputs, which use the patented
OptoMOS architecture, are controlled by a highly
efficient GaAIAs infrared LED.
• High Reliability
• Arc-Free With No Snubbing Circuits
• FCC Compatible
• VDE Compatible
• No EMI/RFI Generation
• Small 6-Pin Package
This OptoMOS relay provides a more compact design
solution than discrete single-pole relays in a variety of
applications, and saves board space over conventional
electromechanical relays.
